Being a builder, my first thought goes to the construction type items: Tile or wood floors, vinyl shower kits, high quality wall paint like Behr Marquis, solid wood furniture, good appliances not cheap rental ones, easy to maintain yard outside like DG, artificial turf and gravel. 

My normal pattern has been to find rehab and rent properties for the cash flow.

I've been in a similar holding pattern. 

I don't know about this cap rate projection, at least in CRe-Retail we project out a 10 basis point rise in cap rate for each year the property ages, so the Cap rate may be 5.5% assuming interest rates don't budge, (probably heading higher as US Govt has to deleverage its last 40yr debt run-up, like we did between '45 and '82, and we did again btwn 1899-1920, same 30-40 pattern going back to mid-1800s)I watched all their videos/podcasts/available webinars.

Everything. 2) Make sure you have a signed contract that is legal and thorough. 3) keep the progress payments relatively equal to the work being done....example - don't pay for tile when you're still doing framing.Go get some bids and then come back and talk to us again... 

The point I am making is the decision the GP makes is circumstantial and very specific to the fact pattern of their particular deal and to tie back to my first post in this thread, who that decision maker really is is important. 

Tax deductible improvements such as drainage tile, terracing, irrigation can significantly improve the productivity and the value of the land.

New LVP flooring upstairs to replace all the carpet, new cabinets and countertops in the 2.5 bathrooms, new fiberglass shower in the guest bathroom, new walk in shower (tiled) in the master bathroom, next lights/sinks/faucets/toilets/etc in all bathrooms, new paint on kitchen cabinets, new pulls on kitchen cabinets, new ceiling fans throughout, and fresh paint throughout.

Most of them are C class with 8 of the 38 units probably D class being in the least desirable area of town, but the pattern is the same.

It is very fact pattern and venue specific.
