There are some differences there in terms of neighborhood but a lot of the same stuff applies.In addition to crime and location close to main roads, I also would look at jobs growth vs cost of living in the area.

Hi Bea,HomeAway has stated that the average management fee is 24%, but that isn't necessarily the average effective rate after additional fees.

When they renew, I do not charge anything additional.

Bet they don't!

Whats the bet cash flow on the NNN property?

Keep the insurance in the homeowners name (you become an additional insured), get a durable power of attorney from the homeowner, and make the payments on time!  

A commercial, asset based loan will probably be your best bet.

Because everyone is looking for one, and if everyone is always looking over their should for the next real estate crash, you can bet there won't be one.

I figure 1031ing is my best bet, but at the same time I get great cash flow currently.

If you do sell within the next three years, you'll probably come out even, as you added the additional loan costs to the principal you need to pay down and your house will may be underwater (assuming you bought at market and there isn't crazy appreciation where you bought your house).
