It keeps everyone on the same page.3) The downside of using a PM who has their own maintenance company is that you might end up with larger bills as it is a profit center for them.

Are there some investors who are making enough profits to participate or are these new investors? 

Question is, was it profitable to do all this?

I would also urge you to make sure you fully understand how they operate , A-Z (from how they make their profit to how many doors they are managing). 

Quote from @Adam Macias: Wholesaling as it is today will be a thing of the past.It’ll truly be strange to even hear people and gurus trying to make big money off it.The more people try wholesaling but then end up not having an end buyer or cancelling contracts or trying weird things like novations, the more all of real estate will be regulated and cause requirements like licensing to be able to transact more than just your personal resident purchase.Which I don't know why hasn't happened sooner.Here's all the states (in red or yellow) requiring a license to wholesale or at least have started the process:Credit: REITipsterI think licensing and regulation is a beautiful thing that should happen if you plan to be an wholesaler and do more than one deal... which is going to be the case for anyone taking this business seriously.Or even it being regulated to need a real estate agent to do more than one deal outside of buying a personal residence.I've had plenty of failed attempts with agents in pursuit of wholesale deals and I know exactly why, it's not because the agent couldn't find me deals, it's just not practical to think there's opportunity for the numbers a wholesaler needs to make a profit on top of everyone else needing to these days.Because the only sellers who truly can sell at a deep enough discount are usually those who ran out of time and just didn't do something sooner with their situation.I know many coaches and gurus will disagree with me but there’s no regulations on youtube gurus and what they teach either.If we look at the current state of the market in hot cities, the availability of online resources to the average homeowner, how many deals can you possibly believe are available at 70% of ARV?

A good place to start figuring out profit/cash flow is to search the forums for the 4 Square Analysis. 

Offer aid and housing options if you're able -- don't try to profit. 

Yes when I looked at my pretax overall profit in the flip it was really close to my pretax salary for the same amount of time.

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.

STR's can be very profitable in certain areas of the state, and rental demand is growing rapidly.
