So the cost for that project was minimal since the materials budget was basically $0 (we already had the tile and grout).

You'd have to spend some time learning your market and setting up a sellers and renters list to minimize risk.

However, as I said above, personally I don't think I'd want the headache of a long distance rehab/rental with a sibling I might not work well with for dubious returns that will be minimal at best.  

I want to try to minimize my time spending on property management by learning all the basics of being a good landlord, from reading all the good books and of course from this forum and all of you.

The rehabs are minimal so they may work as rentals for buy and hold investors.

How exactly does the fact that you use a broker minimizes or "spreads out" your risk?

I don't currently know much of it but I plan to learn to do as much as I can to minimize costs... 

Rehab is minimal--paint and cleaning--$5K max.Finally, seller's loan is 2%--payment is $750/month.

One of the thoughts I just had: asking this question on a forum (where everyone is at least minimally tech savvy) is a little counterproductive, being that my target market would be the landlords that aren't as comfortable doing things on their own online.Does that market exist?

I would most prefer a multifamily property, but that requires waiting, which I hate - and I want to minimize wasted time!
