Waiting periods for a condo conversion can be up to 24-months if you have an elderly tenant in place.Converting a single family to a 2-family is a condo conversion -- you are taking a single family residence and creating two condos.

If no debt and elderly then it is a potential go.

My neighbor across the street - an elderly woman - wanted her birch trees pruned up a little bit.

Granted, it's a nice neighborhood and my parents charge low rent, so I can see why.But we need to remodel that unit, and my (elderly) parents want me to move in there and get more involved in the management of the building ASAP.What are my options in making sure this lady is out by the end of the six months? 

Or sometimes you find an elderly person who has many others using his credit and he has no income left. 

There is another forum addressing seller financing here on BP, and I just had to advise someone of the pitfalls in dealing with someone in a nursing home or an elderly person, would that have been in you booklet?

In Florida for example transitional lists tend to do well because there is a higher elderly population who are all looking to downsize, so just knowing your area and getting a list that fits your niche is the best tip I can give. 

It was poorly worded and inadvertently, I think, prohibited buyers from having foster children or live-in nannies and caregivers or from buying a home to be occupied by elderly parents.

The only cosigners that I accept are parties that are related to the cosigner, ie: adult children, sponsoring adult, elderly parents, etc.Good Investing...

Or find a property where the elderly person cannot mow their grass /  do other yard work and offer them the same labor.
