Same as flipper.....I was and still am a remodel contractor. Still a newcomer to investing, working on acquiring my second deal right now. Hoping to eventually get to the point that I have at least one rehab going all the time, completing one as another deal is closing....Heck, I'd really like to end up with a couple rehabs going at the same time but slow and steady getting there is also my plan. Besides I'm having an interesting time getting offers accepted so far. Few banks at the moment are even giving me counter offers, and I've yet to get one of those to come down near enough to match the numbers I need to make it work and of course counter offer or not, a rejected offer still means I just increase my original offer and try again until I reach my max.
Meanwhile I keep remodeling/repairing on customer contracts and waiting for an accepted offer to purchase. Even if I get lucky enough to fulfill my hopes of always having a rehab/flip in the works I will have to try to balance that for some of my established clientele, most all of my work is referrals and repeat customers.
Besides, it's a money strategy thing I'm also shooting for. I have a separate (brand new though) S corp for purchase/sales and the contracting business for the repairs.
