I sold because when it comes down to it, I think I was returning 8% over the last 15 years which came with headaches, a tree that keeps falling and nearly killing someone, hail storms that keep damaging the roof and increase property values that also increase the property taxes because Texas is 2.2% which is raising faster than rents can keep up with.

I purchased a 3/2/2, 1366 sqft rental home built in 1986 (roof 8-10 years, no pool, smoke alarm, etc) in May 2023.

We've replaced the roof (18.5K, it was never torn off in 100 years) and redid kitchens and bathrooms. 

New roof, solar, paint, lvp in the living room, granite countertops, cabinet handles, fixtures, carpet on stairs and upstairs, refurnished entire house.

Having 100 units under one roof gives you far more focus and economies of scale when it comes to maintenance etc.All your risk is concentrated on one pile.

If any of you could help me determine what kind of property damage I should avoid either because it costs too much to fix or it is just too difficult/ time consuming (things like termites, gas lines needing repair, roofing, etc.).

The  unit is rented consistently and is functional but also needs upgrades, new siding (has 2 layers), Some rooms could benefit from re-wiring and more insulation,   Painting is always an issue as it is not plaster but older thin wallboard. kitchen is fairly new, bathroom could use upgrade, upstairs bedrooms have some pitched ceilings but I don't think based on the foundation/construction it is a candidate for a full second story and it had a new roof a few years ago.

Or one of my favorites... the tenant reports the roof is leaking.

Ins is through the roof as well. 

No... we replaced the roof, why put in a crappy hvac?)
