Plus, my complex had 4 pools, 4 hot tubs, a gym/sauna, and security onsite that kept and held packages. 

That was the biggest reason of how I was able to get a package deal closed at $790,000 that appraised as is at $1,265,000.  

Eventually I’ll sell as a package.

Several third-party software developers make such add-on/plug-in packages for Excel.EDIT: Be wary of any potential analyst doing this without using some type of Monte Carlo simulation or similar technique.

I understand that with a typical FHA loan, only up to a 4 Br can be purchased though in this posting it says two building are "included in a package".

was it a package deal with the house?

@Tom Gimer  in CA its lenders discretion they can choose to let you cure 5 minutes before the sale or at day 5 they can say sorry cut me a check for the full amount..

Waiting for the delivery of my package which should be here by the 8th.

Account ClosedThe 30% you deduct represents 15-25% profit for flipper1% purchase costs3% sales costs3% holding costs3% “fudge factor” for unforeseens (many run this at 5%)Obviously, in higher ARV areas, there is more wiggle room for MAP profit margin at the discretion of the flipper...Then you hafta subtract even more for the wholesaler’s fee!

This is correct, OP.If you want them both then you can certainly negotiate them as a package, but the residential lender will want two purchase contracts, two appraisals, two escrows, etc etc.
