So I proactively replaced them at the beginning of summer so my tenants could enjoy new units.Roof = 25-30 yearsHVAC = 4000, 20-30 yearsFlooring = 1500-2000, 10 yearsPlumbing = 4000, 20-30 yearsFixtures = 1000, 10 years (I'm assuming this means all faucets and light fixtures)Water heater = 600, 10-15 yearsAppliances = 400, 5 years (although I'm not a big fan of supplying stove/fridge)Components = 1000, 15-20 yearsStructure = 10000, 30-50 yearsKitchen = 3000, 20-30 yearsWindows = 3500, 30 yearsPaint = 1000, 5-7 yearsLandscaping, 100 per yearOverall, the net is that as long as you are on top of maintenance items, make repairs and proactively replace things (and keep adequate reserves to do so), your $30k house will continue to generate cash flow like a little oil well. 

It has the downsides of being somewhat invested in oil and being vulnerable to hurricanes, but from what I've read both of these downsides are mitigated by Houston having a pretty broad job market nowadays, and buying homes outside of flood zones.

That coupled with the supply chain problems and the Ukraine-Russian war effect upon grain prices and oil prices suggest that we will be in for a bumpy ride for a bit. 

For example, here in Northern NJ, it's common to inspect for in-ground oil tanks during the inspection process.Fourth, the agent needs to provide excellent client service to out of state clients.

We'll know what BP is, however to most of the world it's a big oil company that had a huge spill last year.

The older victorians you have major issues because of age.Knob and tube wiring,galvanzied pipes,foundation issues,asbestos,oil heating tanks,mold,radon,etc.How many other properties are in your name??

wood, electric baseboard in some rooms, oil furnace which is a lennox giant behemoth that does not look like it is in working order.

Enjoy and have a coconut for me because like you, I'm not in it for the drama.
