Quick answer: A second mortgage can provide junior capital against the development site, subject to senior-lender consent, intercreditor arrangements and sufficient equity. It is not free developer equity: the additional interest and fees must be included in the feasibility and cost-to-complete.

Questions borrowers, investors and developers commonly ask
- My senior lender is short $300k — can a private lender take second mortgage security?
- Does the first mortgage lender have to consent?
Priority and control are critical
The senior lender generally controls first-ranking security and may restrict junior debt or require a deed of priority.
Junior debt increases break-even
Every dollar of second-mortgage interest and fees reduces project profit and can magnify downside if values fall.
