Then import them to Excel and do a double search for flips.

Can I usually get back the money invested in fees (contractor's opinion + closing costs when choosing to double close) when charging my wholesaling fee?

But, it becomes a double edged sword if you want to Refinance out of it.  

Row homes are operate at a fraction of the operating costs/repairs, Philadelphia's tax is a fraction of NJ and the price point is doable.Also, don't rule out a partnership - if you doubled the investment you would upgrade everything.

Soon enough the neighborhood caught fire (or was it already on fire) and now properties are at least double what they were four years ago.

If you were doing 8K miles per year the depreciation would be the same but mileage would double so that'd make more sense to do mileage with a longer hold period. 

I get what you and @Andrew Johnson are saying and what I am trying to do is to get off the lists of the "wholesale companies" who are basically agents doubling as re-wholesalers.

If I want to close on a property that I'm putting under contract, but I don't want to do an assignment because Im making too much of a spread, how can I double close on the property with no money???

In my estimation, PMs using their vendors usually charge double or triple the market rate for the repair, so that would be around 100% markup.

A Solo 401(k) may be exempted if the deal is structured properly.A fund that derives its income from the development and/or re-development and sale of property would be producing trade or business income that would generate UBIT liability to both IRA and 401(k) investors, and if leverage is involved, a double-whammy with UDFI as well for the IRA investor.
