So I’d rather ‘self-insure’ against those things and keep my bank account a bit padded for when/if those things arise.

I don't have a ton of experience, only one live in flip, I have managed a handful of small construction projects at a previous employer, I managed the entire engineering park project at my current employer which included construction of an 11,000 sqft pad, a 3500 sqft facility with all necessary plumbing and electrical, I also personally designed an managed the installation of our custom chilled water delivery system that is required for certain tests.

Pad mapper and hot pads show live listings that can be compared to the unit you're comping.

I think you need to pump the brakes a bit and get some real estate investing education under your belt.

I'd love to work closely with someone as a project manager (working for peanuts) to turn a building around for massive equity gains just to see how it is done and pad a resume.

For example, the $1.80/SqFt for carpet includes removing the existing carpet, minor repair work on the sub-floor and a new pad and carpet installed.

Or 20-30k per finished unit for a 15% net net net cap rate after mgmt maint vacancy pads

This slightly increases the cost on the buildings, erection and building pads.

It seems like it's just a matter of time before they brake and therefore I will get a Home Warranty for the house

Generally, larger parks of 100 spaces or more are more attractive, but you’ll find economy of scale will start to work in your favor once you get north of 40-50 pads.
