First of all, congratulate on your success on a business. It's not easy to start / run / let along a profitable small business. Most people can't start a business, let along run and get a business in the black. :)
I saved my post for a few days and wasn't able to find it so some of the info might already be covered by others...
I think some of previous posts already pointed a few things you should be aware before you jump in. The main point - do you have financing ready? do you know any banks / credit unions / private parties / hard money lenders which will loan you the money while you work / rehab the house(s)? Without a day job, how do you plan to qualify for financing because they want to see your W2 or previous tax returns? Do you have enough deals to qualify for those loans, and what are their terms? Most people stick with Fannie Mae / Freddie Mac financing for their 1st 10 deals as these provide the best term (interest and down payment requirements). Once they pass their 10 deals they will work with banks / credit unions on commercial / portfolio loans, which will usually be higher interest rate and down payment requirement.
In terms of capital needed, it all depends on the area you want to invest in. Where I live I will be luck if I can find $300-$400k houses to work with. So if the average selling price is $100k, you probably want to have at least that much to start with, depending on what you can get and how much you need to rehab the house. Even if you use hard money lenders, you will still have some skin in the game because they won't give you 100% loan. You can always find money partners to learn the ropes, but you will have to find your partners from your existing contacts who know you, or establish new relationship while you prove yourself.
Good luck going down the path. Wish you success!
