There are a lot of extra costs that go with home ownership-property taxes, repairs and maintenance, etc. 

My guess is your development (not including infrastructure and non recurring costs) even in your large volume is over $450k but I have less clue as to how much is structural (issue with me doing rehabs and not development).  

There are other solutions out there and I'd like to emphasize that people shouldn't jump to paying for a bookkeeping service that might cost 3% or more of their gross revenue.There is Quicken for business and Waves accounting, and likely many other software programs.

I feel pretty confident about the flipping process having done 4 full rehabs as well as several more minor ones.

"Off market" can be good if it fits into your strategy of the time and effort outweighs the actual cost savings.

During that time they supposedly found a leak which was beyond the scope of the maintenance  and i had to pay a plumber to come in saturday morning while the guests were there. thats on top of the "deep clean" which cost $300 and was somehow done in a couple of hours. 

Paying a deposit is cheaper than the cost of moving their home to another park, if they can even find one. 

It seems there is a significant discrepancy with the cost of housing (very high) and rent (much lower then the cost of housing).

I'm also a Reatlor® and work almost exclusively with investor clients, so this is my area of specialty.I recently began working with Account Closed and his team because beyond just taxes, they also advise and provide valuable services such as cost segregation studies.

@James E.Hi James,I'm not a wholesaler... just an investor who has dealt with wholesale deals.My broad perspective is that wholesaling is a marketing job - where the wholesaler (on the surface) is trying to help a seller, but ultimately is trying to do that in a way that ends up costing the seller more money than it should have, had the seller taken more traditional means to achieve that sale.
