Quote from @Mason Jacobs: @Eric Goldman had a good point, if you don't rent it out no one will lend DSCR, you might get a local bank but a DSCR doesn't work if you don't have it rented!  

Again, if your $250k is true, and includes all the electrical upgrades, new plumbing runs, potentially new foundation pour (since I assume the existing garage slab is not capable of supporting a new two story house), I am guessing since I don't know the market, but assume you will have a lot of equity by completing the project.

One of them I have used personally. 

Yes, last year and that’s all over with now.

All about curb appeal!

All the fine print came in subsequent e-mails.

So, I'd look to the other properties and ask whether the ones on the street also had only street parking versus access to a driveway.

Zoning Ordinance ExceptionsSome properties in the target zone don’t meet the minimum lot area or width size requirements under the zoning ordinance, yet houses exist on smaller-sized neighbor lots.How could these properties get approval for development?

Everyone has their own room and a bathroom and they share common space such as living room, dining room and a kitchen and they are one the same lease.

Think of all the things that could go wrong and see if the lease addresses them: unauthorized pets or tenants, early termination, security deposit, lease violations, late rent, eviction, lawn maintenance, parking, etc.5.
