I don't think you need to take a picture of each wall, but of each room and each noteworthy item that was damaged is really helpful. 

Costs ran significantly over on both of these items and not being in the area it was not possible for me to add my experience in renovations to lowering them. 

Hi everyone,Over the past six years, I’ve built a portfolio of 70+ properties, primarily single-family rentals.

The only exceptions I can think of are a lack of experience frustrating your financing process or where the GC has such a well established brand that a buyer will pay a premium for a home built or renovated by that particular contractor.

You can also target a SFH that has a casita or has room for one to be built.

Typically those are built with 4 units to an overall structure. 

Quote from @Jenni Utz: You have that built-in equity on the deals that are off-market.

I for one built a simple chrome extension to see if the mortgage is less than rent and accordingly provide that information on every zillow listing page.

I plan for a time when they can be there and check in and make sure there aren't any maintenance items they haven't told me about.

I own a single-family home built in 1950 here that I rent out.
