Basically, if it is within 30 minutes in any direction of Coral Gables (to pick a central starting point) and the area isn't rough (look for typical indicators....plywood over windows, bars over windows and doors, chopped up cars in the front lawn, lots of "outdoor" furniture in front of the house, etc.), you'll be able to sell it after rehab.Best price range?

I'm young and unattached and am ready to pick up and move across the country if that's what it takes.I've been researching each state individually and an forming my own opinions about which ones have the best laws and ways of doing their auctions.I'm strongly considering Texas, Nevada, and Florida.

Let agents work for you, you can be lazy, pick and choose the deals you want, make low ball offers, make one or two deals a month, flip, wholesale, assign, oh...... the sweet glory of it all, the freedom to invest in real estate with no money or OPM.....the pleasure of investing and making offer and cashing equity profit checks is just overwhelming. .......!!!

I can pick a brain like nobody's business!
