I've bought and fixed 2 houses with him and they are rented.He got brought a portfolio of mixed residential and commercial units that are very underented and need mostly cosmetic upgrades. 13 residential, 6 commercial, and a lot currently being used as parking.

The flip was initially supposed to be a 30 day turn around due to minor cosmetic upgrades.

I transitioned a single family primary into a rental as well and now within less than a year and a half have upgraded and rented out two single families and a duplex and am looking to get into at least a total SFH flip and a larger multifamily this year with investors.

Yes, you can claim it as maintenance/repairs/upgrades - I'm pretty sure, but check with your CPA3.

As for strategy- i am currently in contract to sell my 10 plex and upgrading to 20 units.

Since the building Is being updated make sure they are making ADA compliant for required parking outside and upgrades inside. 

The doors are coming in early and you were able to save them $2000 to cover the upgraded hardware they wanted, tell them. 

You'll need to upgrade your account to do so.

There are going to be repairs and/or upgrades that need to be made to the property.
