As luck would have it (or by the terms I chose to use) it's prettyeasy math:$800 = $80,000 financed amount @ 10.5% for 20 years."

To me it's basic math.

The bottom line is, do your homework.

I'm not really worried about my return so far--- just interested in learning the math...thanks,Jimmy

I try to invest based off math and risk instead of what other people tell me is a good idea :) @Darrin Carey I don't have the $$ to have a team start working for me but this may be something I consider in the future.

That's really a math problem.

My math says $285K - 5% Commission (no one should ever pay more!)

I would suggest doing a little more homework on rent rates in that area then just taking what the sign said as gospel.Get on rentometer.com and it will give you an idea of what houses have rented for in the past.Also you can use zillow, hotpads and craigslist to find out what people are currently asking for rent today.

I have a good credit score 760+, but do currently have a mortgage on my current home.

(or maybe so.. but you'd better do the math for the worst case scenario)
