You're still paying the same amount for the same labor, except the NOI is significantly different due to their market rents.Personally I think flat rates should always be used.

As far as taxation goes, everything is generally just considered active income except for when the loan is resold, especially after holding for 1 year.

The borrower is not allowed to voluntarily or involuntarily transfer the property without the lender's consent, except for transfers allowed by law.I've purchased properties at HOA lien foreclosure sales subject to senior mortgages, which is similar to your situation except I was in an even weaker position.

No one wants to go on vacation and feel like they are in Grandma's house (except maybe Grandma).3.

I've gotten 3 conflicting answers and my accountant has no idea:  a) I owe nothing because I lived in the building b) I only pay on 2/3 of my portion of the gains because I lived in the 3rd unit c) I can't claim the owner-occupied exception at all because the property was owned by an LLC. 

Sometimes, the best deals you make are the ones you don't make...or the properties you don't get.You're not doing anything wrong here...except not realizing that getting offers rejected is a part of REI...and sometimes it's a successful part of REI.Keep firing offers...and deals will come.

Except not mortgage payments but mortgage interest, as well as other expenses like property taxes, insurance, HOA, utilities etc.
