Gifting equity in a house may be more trouble than it is worth if you are not near the life-time exclusion1) Potentially having to get the property appraised everytime an equity is gifted2) Having a title company update the title every time3) Exemption of the gift tax return is normally for cash gifts below the annual gift tax exclusion, you may still need to file if you gift non-cash4) If there is partial ownership over several years, having to properly pro-rate certain items such as real estate taxes, mortgage interest and rental income if the property is a rentalBest of luck 

Suggest you check in with him/her on this additional service as your attorney is already intimately familiar with the file and you can often give them pre-authorized amounts to settle on vs trying to squeeze all the blood from that turnip. 

If you were able to increase the value of the property significantly after the rehab, then you could bring the deal to a community bank  to refinance and take the hard money lender out.You keep all the equity and don’t have to file a partnership return for your annual tax return, which can be costly.

You don't need file any paperwork with courts, etc?
