Watch for a sale, don't worry about a warranty as they will all last about the same length of time. 

When it comes to 1099's, S-Corps, etc. the length of time most banks care about is much, much, much longer.

I can't remember off the top of my head, but I think the max length term they can stay is 3 months before they have to be moved out.

We have also flipped almost two dozen of them before the bubble burst.The typical national home is a 3 BR one bath. and the exterior length and width were built with 4' sections.

You'd run the risk of being black listed to purchase that property as the buyer being privy to sellers private information could be construed as a violation of arms length.

Valid sales = arms length transactions.

If I bounce from unit to unit with stays of reasonable length, and the LTB allows it, I'd probably be looking at 2 years to finish, and by then I'd have planned to have moved into a duplex, then moved into a SFR for ourselves.I feel my hands are tied...

What is your average lease length?

My ads are pretty clear about the requirements, move in dates, lease lengths, pet policies, security deposit, etc.  

LOLReading between the lines of the lonestar URL if this investor does just one seller financed note, attempts to do ATR (full doc) and optionally (but you are well served) use a Licensed Mortgage Loan Orignator to be arms length origination, then less to worry about.
