A savy agent sensing a situation like that might simply ask for proof of funds before showing the house which a nosey neighbor is unlikely to have.

Otherwise, you won't have the extra funds necessary to cover the rising costs of goods and services in the future.What causes rents (and prices) to increase?

Perhaps as a syndication or credit fund?  

If lenders reject a HELOC due to lack of W2 income, explore DSCR loans, private lenders, or partnerships to fund new investments while retaining your current property.

If you’re confident managing more complexity and have the funds, a small multi-family property could yield higher returns.

Their only involvement will be funding the project. 

I brought in a partner who funded the downpayment. 

However, if you're that tight on funds, you may be better off slapping yourself haha.

Wegg,I believe this thread was started by you & correct me if I am wrong, but your situation doesn't seem to be about building 2 homes, it's about issues with funding the new construction project, right? 

Quote from @Mike Klarman: Virginia, I would love to hear about a deal or two that you funded.
