I have contractors, property inspectors, and property managers tell me about the property's condition and rent-ability.

My concern is ability to manage the properties while living 80% abroad. 

In the condo boom I noticed a lot of basements being converted into condo's so I would imagine there being some ability to convert an unfinished basement into a legal apartment.

You could start advertising now so you can cover as soon as the vacancy occurs and make the ability to co-operate with showings a condition of any agreement.

I guess this would be considering a wrap around mortgage since I'd try to keep paying on my mortgage - though I do have the ability to cover if they were to activate that rare due on sale clause.So my questions are for anyone who has had experience in structuring seller financing deals:1) My initial thought would be to structure it to parallel my own ARM to keep her payments low for 5 years (close to what she's been doing for rent) and have a balloon payment in 2020.2) What kind of interest rates are usually charged in this situation?
