Although there is potential profit in this kind of profit, there is also more risk associated as the repair costs can pile up quickly and create a scenario where you have invested more into the property than the repaired property would actually be worth. 

If I owe $350k mortgage and I take out $100,000 HELOC and spend it on say a 6 month CD,And then I sell the house for $700kI would only have $250k profit right?

If you adopt a solo 401k as a Sole Prop you won't have to run payroll and incur payroll taxes and you can still do $23,500 plus 20% of the profit as a profit sharing contribution.

Suggesting to them buying their house for a wholesale range offer or lower dependent on the extent of the rehab, then having a contract in place that gives them a percentage of the profit to help get them back on their feet, paying off debts etc.

"Just signed another deal and making XYZ in profit!!!"

@Grace Tapfuma I have no idea how things work in Australia but if I were you in the US…Don’t sell the business.Businesses usually sell for a much lower multiple of their products income than real estate does.To be honest, you’ve built out a lot of infrastructure to create a successful business and maybe reinvesting in it would create a much better return on investment.For which you could reinvest those future profits into real estate, once you’ve scaled your business into a money making machine that isn’t so dependent upon YOU to drive the bottom line.I had a friend (38 years old) just recently sell his medical device company for $30M dollars and now he’s using this chapter of his life to passively invest in real estate ventures.Meanwhile, I’ve been toiling out here for 19 years as a real estate investor and I’ve built a portfolio worth $18M and have a net worth of $5M at 41 years old.Sometimes the grass isn’t greener on the other side.Correct me if I’m missing something!

Theyre out there, but they are largely impractical and not viable except in the most profitable deals.

When you charge under market rent, the IRS deems that you do not have a profit motive and, therefore, disallows all rental expenses. 

We built a single family home version of a 2 bed 1 bath with surface parking at cost with no profit all in with land for 175k in newark ohio, a suburb of columbus ohio. when we push that to 3 units and closer to the city for our build to rent model the numbers go way better. a 30k slab for a single family home is 30k, a 30k slab for a triplex is 10k a door. we designed a 2 bed 1 bath design at 668 sq ft and it's very good layout even I would live there, but I would never build anything that small again. there's no economies of scale. you need density and shared lines, resources, shared roof shared slab, shared windows, etc the cost goes way down.
