If you're going the umbrella insurance route, make sure it will cover you for several things including just the routine slip and fall (like mold or earthquake).

It's on the job training.Yeah, what was supposed to be a 30 minute routine visit was a 5 hour experience.

We can usually do the whole routine of 'move out, move in' in under a week while working our normal jobs for under $1k.The closest idea that I can find is this: https://passiveincomemd.com/buy-one-property-a-year-and-retire-early/(main distinction being that we live in these houses and pay a lower DP)The specific questions that arise in my mind are as follows:Why don't other people do this? 

Its a 5 br 2 bath that needs cosmetics and appliances for 80k.

We've made significant cosmetic upgrades to 3 of the 4 units over the years.

At first we thought we'd remodel a couple of units and then do the rest one-by-one, but as we got into the project, we realized that we needed to touch nearly every surface and redo the electrical service, so we forged ahead with cosmetic updates to all the units.

Our renters stay for years on end, but every time the property turns over, we try to make at least one cosmetic upgrade.

We fixed that immediately and have done cosmetic upgrades to 3 of the 5 units.

The building is in good shape but very original, cosmetically.

When we close we will take care of the cosmetics.
