Why lenders become cautious
A mortgage lender must be able to answer two questions:
Can the borrower repay the loan?
Can the property be sold within a reasonable period if repayment fails?
A non-standard property can weaken the second answer even where the borrower has strong income and credit.
The lender may be concerned about:
Limited buyer pool
Uncertain valuation
Poor insurance availability
High repair cost
Legal-use issues
Environmental exposure
Seasonal access
Specialized construction
Lease restrictions
Remote location
Long marketing period
Main non-standard property categories
| Property | Main underwriting concern |
|---|---|
| Rooming house or student housing | Tenant turnover, legal use, management and maintenance |
| Seasonal cottage | Access, water, heat, insurance and resale season |
| Vacant home | Condition, vandalism, insurance and unknown occupancy |
| Estate property | Legal authority, deferred maintenance and closing timing |
| Major-repair property | Cost to complete and current habitability |
| Environmental concern | Cleanup liability and marketability |
| Legal non-conforming use | Continuation rights, rebuilding and lender acceptance |
| Unusual construction | Appraisal comparables, durability and insurance |
| Leasehold property | Lease term, assignment, lender access and expiry |
| Remote property | Smaller market and limited comparable sales |
| Contaminated land | Remediation cost and legal/environmental liability |
| Specialized commercial asset | Narrow alternative use and limited purchaser pool |
| Vacant land | No current income or completed improvement |
| Mobile, floating or modular structure | Title, permanence, site tenure and resale |
Marketability is not the same as value
A property may have an appraised market value but still receive conservative lending because:
Sale could take longer
Buyer financing may be limited
Repairs are required
Property insurance is restricted
Use appeals to few purchasers
Comparable sales are weak
Appraisal depends on extraordinary assumptions
The lender may use:
Lower LTV
Lower accepted value
Shorter amortization
Larger equity contribution
Full appraisal
Specialized appraisal
Private or alternative product
Additional collateral
Worked accepted-value example
Assumptions
Appraised market value: $1,000,000
Property requires repairs and has limited marketability
Lender-accepted value for its internal analysis: $850,000
Illustrative maximum LTV: 65%
Existing mortgage payout: $400,000
New lender, appraisal and legal costs: $15,000
No other liens
The accepted value and LTV are illustrative, not universal policy
Variables
AV = Lender-accepted value
MLTV = Maximum lender LTV
MSD = Maximum secured debt
EP = Existing payout
C = Transaction costs
NE = Net new funds
Maximum secured debt
MSD = Accepted value × Maximum LTV
MSD = $850,000 × 65%
MSD = $552,500
Net new funds
NE = $552,500 − $400,000 − $15,000
NE = $137,500
Result
The owner may see gross equity of:
$1,000,000 − $400,000 = $600,000
But the illustrative structure produces only $137,500 in net new funds.
Interpretation
The lender’s accepted value, LTV and costs—not gross appraised equity—determine usable financing capacity.
Rooming houses and student housing
A lender may investigate:
Legal number of rooms
Zoning
Licensing
Fire code
Lease structure
Turnover
Property management
Utilities
Maintenance
Insurance
Marketability as an ordinary residence
TD’s July 2026 broker policy treats rooming houses and student housing as restricted properties considered only on rare exception because of turnover and higher maintenance risk. It also treats non-conventional construction as exception-based.
Classification: Named-lender property policy.
Source: TD Broker Services Information Kit, updated July 6, 2026.
Material qualification: This does not mean every lender declines rooming houses or uses TD’s exception criteria.
Seasonal cottages
The lender may consider:
Year-round or seasonal access
Potable water
Heating
Foundation
Wastewater system
Winterization
Remaining economic life
Recognized recreational market
Insurance
Rental use
As one named-lender example, TD maintains a separate cottage policy for certain properties that may lack year-round access or ordinary residential features. It may require evidence that the property is in a recognized vacation area and applies its own marketability, product and value limits.
Vacant and estate properties
Vacancy may result from:
Estate administration
Renovation
Relocation
Tenant departure
Power of sale
Construction
Long listing period
The lender may require:
Vacant-property insurance
Property inspection
Heat and utility confirmation
Security or monitoring
Repair estimate
Estate trustee documents
Legal authority to mortgage or sell
Evidence of taxes being current
The borrower’s right to act for an estate must be established before financing can proceed.
Properties requiring major repairs
The lender may distinguish among:
Cosmetic renovation
Deferred maintenance
Structural defect
Fire or water damage
Uninhabitable property
Incomplete construction
Building-code issue
Possible structures include:
Purchase-plus-improvements
Construction draws
Holdback
Private completion loan
Land-value financing
Sale
The appraisal should identify whether value is current or “as completed.”
Environmental concerns
Potential concerns include:
Former gas station
Dry cleaner
Industrial use
Fuel tank
Automotive operation
Contaminated fill
Neighbouring contamination
Mould
Asbestos
Underground storage tanks
The lender may require environmental consultants and further investigation.
A Phase I Environmental Site Assessment does not guarantee that no contamination exists. It identifies potential environmental concern based on the scope of the assessment.
A Phase II or remediation plan may be required.
Legal non-conforming use
A legal non-conforming use may have existed lawfully before current zoning changed.
The lender or lawyer may examine:
Evidence of prior legal use
Continuous use
Municipal confirmation
Rebuilding rights after damage
Insurance
Marketability
Whether use has expanded or changed
A borrower’s statement that the municipality “has always allowed it” is not adequate evidence.
Unusual construction
Examples include:
Log construction
Straw bale
Earth shelter
Converted church or school
Shipping-container construction
Dome home
Off-grid residence
Modular building
Floating home
The lender may require:
Specialized appraisal
Engineering
Building permits
Insurance confirmation
Comparable sales
Evidence of market acceptance
Larger down payment
Leasehold property
With leasehold property, the borrower owns or mortgages an interest in the building or lease rather than ordinary freehold ownership of the underlying land.
The lender may review:
Remaining lease term
Renewal rights
Assignment
Ground rent
Landlord consent
Mortgagee protection
Lender access after default
Right to sell the leasehold interest
Prepaid or recurring lease payments
Relationship between lease term and mortgage amortization
TD’s current named-lender policy considers defined government or Crown leasehold properties on exception. It generally requires the lease term to exceed the mortgage amortization by at least five years, a full appraisal and an assignable lease that permits lender security and access.
Classification: Named-lender policy.
The acceptable landlord, lease term and amortization relationship differ among lenders.
Remote properties
A remote property may present:
Few comparable sales
Limited local employment
Seasonal roads
Long emergency-response times
Higher construction and repair cost
Limited internet or utilities
Small buyer pool
Restricted lender service area
The lender may apply a lower accepted value or LTV even where the home is well constructed.
Specialized commercial assets
Examples include:
Place of worship
Banquet hall
Funeral home
Marina
Golf course
Campground
Private school
Hotel
Theatre
Automotive facility
Long-term-care or treatment facility
These properties may be valuable to the current operator but expensive to convert for another user.
The lender therefore considers both:
Value in current use
Value and marketability under an alternative use
Non-standard property decision tree
Property does not fit standard lender policy
↓
Is the issue legal, physical, environmental or marketability-related?
↓
Can the issue be verified or corrected before closing?
Yes → Obtain municipal, engineering, insurance, appraisal or legal evidence
No → Continue
↓
Does a specialized institutional or alternative lender accept the property type?
Yes → Underwrite borrower and property under that policy
No → Continue
↓
Is sufficient equity available for private financing?
No → Purchase or refinance may not be viable
Yes → Continue
↓
Will the private loan correct the issue and create a conventional exit?
No → Private financing may only postpone the problem
Yes → Structure short-term financing around the corrective work and exit
What the underwriter is thinking
The underwriter is asking:
Who would buy this property after default?
Could an ordinary purchaser obtain financing?
Is the use legal?
Is insurance available?
Does the appraisal use enough comparable evidence?
Are repair costs known?
Can the property be occupied?
Is access reliable?
What rights does the lender have under a lease?
Is environmental liability possible?
Would the property lose value if its specialized use ended?
Does the proposed loan correct the property problem or merely borrow against it?
HopeWell Case Study
Harcourt leasehold self-build in a remote location
A borrower was self-building a principal residence on leased land in a remote Harcourt-area location.
The file combined:
Leasehold land
Self-build construction
Remote market
Poor credit following a medical issue
Temporary interruption in employment
Existing debts
Institutional financing was unavailable during construction.
The file was structured in two stages:
Private construction financing to complete the home and consolidate debts
A-lender refinance approximately seven months later
By the refinance stage:
Construction was complete
The borrower had returned to work
Credit had improved
Leasehold land remained a major obstacle, so the refinance had to be matched with an A lender whose policy specifically accepted the lease structure.
The underwriting lesson: A non-standard property may become institutionally financeable when construction, income and credit problems are corrected, but the remaining property-policy issue still requires the correct lender.
Pattern We See
Unique-property files rarely fail because the property is merely “different.”
They fail because no one has answered:
Is the use legal?
Is it insured?
How will it be valued?
Which lenders accept it?
Can it be resold?
What evidence resolves the concern?
A specialized lender may accept unusual collateral, but it still needs a clear risk explanation.
Common Reasons Files Fail
Borrower assumes appraised value equals lender-accepted value
Property use is not legal
Insurance cannot be obtained
Repair budget is incomplete
Environmental concerns are undisclosed
Appraisal lacks comparable properties
Access is seasonal or legally uncertain
Lease expires too soon
Lease cannot be mortgaged or assigned
Estate authority is incomplete
Rooming-house licence or fire compliance is missing
Property depends on one specialized operator
Remote property is submitted to a lender with no location appetite
Private mortgage does not correct the underlying defect
Future sale assumes an ordinary buyer can obtain ordinary financing
Important Warning
A high-equity property can still be unfinanceable where:
Title is defective
Insurance is unavailable
Environmental liability is unresolved
Lender cannot enforce or sell its security
Current use is illegal
Property has no dependable market
Collateral must be legally enforceable, insurable and marketable—not merely valuable to its current owner.
If You Remember Only Three Things
Non-standard property underwriting is primarily about future marketability, insurance, legal use and lender exit.
Appraised value can differ materially from the value a lender is willing to recognize.
Private financing is most defensible when it funds a specific correction that makes the property saleable or conventionally financeable.
