One golden rule I follow,if it takes a long time to fix/replace when it breaks, don't buy a cheap one.Imagine, this thing breaks in the middle of your peak season and the people who can come out to rebuild are 2 weeks out....It takes at least a day or two to build something like this even if you are super skilled.

It sounds like you're really ready to dedicate time and energy into educating yourself about possible investments and I love that.

The bathroom and kitchen were replaced.

I haven't sold yet, I've been analyzing property to get a head start on the 45-day timeline of identifying the potential replacement property (and because I enjoy analyzing property). 

If that's the case look into finding a handyman, and make sure to shop around for the best price.Stuff I have ran into:lost keys/lockpicking [hired]broken washer [fixed myself]shower door [fixed myself]AC clogged [hired]Microwave broken [replaced myself]holes in the wall [fixed myself] Thank you!

Being an agent will take time to replace your income, 1-2 years.

What @Mohit Gupta says here sounds good to me 

Fridge door seal is cracked in several areas needing replacement.

Replacements if need be?

Get replacement cost hazard insurance along with an umbrella policy of at least $1M, probably double in your area.
