Recently while looking to buy a personal residence, I ran across numerous homes in a very desirable area that have recently been abandoned and not yet on the market.

If its in a highly desirable neighborhood then I wouldn't worry about it as much.

They are a couple in their seventies, so I see their obvious aversion to having the landlord coming around to take care of things as evidence of their desire for privacy (see below about dementia)--I don't think they're trying to hide illegal activity, for example.

I understand the desire to go elsewhere to find deals on residential.

The architect we used here also acts as a permit expeditor, which is to say... he will walk the plans through, has relationships in the department, and knows exactly how much info to give to get the desired permit.

It is very difficult to make that change based on your desires.

Made an offer on a Fannie Mae property yesterday which I desire for my personal home.

A letter saying you moved in for about any reason is good too, as an owner, you really don't need a reason, your desires are good enough.

The building is in a highly desirable area with rising rents and low vacancies.

. , what EVERYONE here is forgetting to mention is that EVERY transaction regarding seller finance has come under new nationwide laws in January of 2014 called the Dodd-Frank act almost make it illegal for a normal person to sell on ANY type of seller-finance deal.Seller finance deals was a way for people with less than desired credit to still become a home owner.
