Anything extra is gravy at the end of the year. be conservative.2) Just model the potential increase into you numbers. 2%-5% annually3) Where in the loop?

When they call looking for a reference I make them to a bunch of extra stuff, too. 

We did not use any extra sub flooring but the existing flooring base was adequate. 

Biggest concern would be zoning and permitted uses. 

The extra $25k is to cover attorney fees, CPA fees, and other things.  

I agree with Bob too, maybe ask for some extra security or rent upfront.

I would look for deals that can cashflow on a 15 year mortgage, then pay a little extra if you can.

Of course I could just keep the detached for my own use but if I can get extra rent why not!   

The first I still owe $150,000, second I took out of $150,000, and now I buy a third home worth let’s say $400,000 and use the $150,000 I got from cashout-refinance, as a Down Payment for the one Im buying worth $400,000 would I really get the extra $250,000 for the 3rd Mortgage or no???

This had been permitted, no one asked him to stop because the unit was in limbo due to my mother not wanting to clear out my father's equipment.
