For around 85000, you can get something which will command 1150-1200 rent, but the repairs will probably be more in the 7 or 8000 range.

Im thinking it would cost around 75-80k and would command 800-1000 per month rents.If I buy a sfr im assuming the cost to be 90 -110000. 100 percent financing. with an interest rate around 4%.What are your thoughts?

There is no strategy that is so unique or informative or secretive that someone with a bit of creative thought, one with logical thinking attributes could not figure out having a good command of basic real estate practices.Now, I'll yield to marketing, yellow letters, advancing and promoting yourself, phone systems, the generic business stuff that is not really so much an issue in RE, or such hardly regulated areas.

I use Short Sale Commander to process my short sales and it is very user friendly.

Just don't let it command you.

What ever hat you might wear in a N/P circle you need to be viewed as the expert in your area to command respect of other participants and have the ability to lead them in the direction needed to accomplish the mission.
