Concentrate on securing a quality deal as experienced real estate investors are not going to be sold by a green 19 year old.

I concentrated on properties with high equity.

I would like to eventually retire from programming and concentrate on this and other things.I am still reading books and stuff.

You need to become an expert at what needs to be done if you are going to concentrate on fire damaged properties.If you have the energy and the expertise you may try contacting the city you want to invest in to find the owners who have money being held for this purpose.

I would encourage you to concentrate on that and not worry about diversification.

Your numbers helped alot.I think the problem is I was concentrating on a 15 year fixed at 3.5% and with Prin., int., taxes, ins.

If you're staying local, I recommend checking local university MBA programs as many business programs have a concentration of real estate.

Might check on the parking requirements as the concentration could be higher for multi-family.As Wayne mentioned you'll have a minor subdivision project changing the legal descriptions to a common lot, that can be political.

Do I concentrate in solid mechanics, thermal/fluids, manufacturing and materials, aerodynamics, etc?
