If you do not manage the project properly time can eat away all your potential profits.

But $651 would not satisfy the loan and release the lien, as there is a prepayment penalty, and I have a faxed official pay off quote from them that's in the mid 700K's.The attorney who arranged the modification has not returned my calls, so I'm really not sure how the principal grew, but I'm guessing it is indeed a penalty, or related to the terrible terms of the mortgage.So indeed, if there was an overage, it would likely be a small amount of money.I appreciate your suggestion, but that would yield something like 10 - 20K, but I'm still pretty sure there is a way to net 200K - 400K if structured properly. 

@Rasheen Johnson Having an attorney opinion based on your state law is always the best choice to ensure everything is kosher.

My rental home has a messed up approach to the driveway that was not properly patched by the previous owner and I didn't have the funds to fix it while I lived there.

Yes you can enter the property and provide access to PGW if you give the tenants proper notice according to your lease.

To be done properly cost segregation should be done by a construction engineer or architect with knowledge of the relevant tax code.

I think it depends on location, quality of rehab work completed and if the home was properly remediate (TDI certificates, etc.) 

Otherwise, there are generally no strict caveats here as long as you get the proper advice on moving the funds an setting up the correct entity for ownership of the asset.

This is challenging when the County says they can’t find it when givin the proper address

Are you going to be able to get a building permit without doing a proper conversion?
