The fact that she has a steady job is not a killer.....she has her own household to pay for and I’m sure she could show she couldn’t pay for this mtg too.In any event, the daughter will most certainly have to sign the deed and most lenders would have required her to sell the purchase contract, since it would be meaningless without her signature.

@Neri Bermas There is no single answer to your question, as it can depend on where you live, and what you are looking to do more precisely. 

I would agree with most of what you said but there is a difference between a single family and multifamily in terms of rental rates and turnover.

If I were single, I'd be doing it right now.

Current tenant has been there 2 years, is now a single mom and has a good job as a nurse, but is constantly late on rent. 

I don't know about the specific add ons you listed, but I do know that my insurance went down when I switched from a homeowner to landlord policy on my single family homes. 

That said, although I think it's one of the hottest parts of San Diego, I still would be wary as a single woman living in parts of Sherman/Grant Hill/Bario. 

If single family home do a survey and check for boundary violations etc.Unless you are getting a sizable discount this may not be worth the effort.

@Jackson SandlandI don’t imagine a single business would have a real effect on property prices .

Most of the cities and towns you listed are mostly filled with single families, though.
