I have many corporate and high-value tenants that do this.We hold advance rent in escrow, and we treat it as a deposit, then we release installment payments when that months' rent is called due. 

Get to know people in the various trades (plumbers, electricians, carpenters, painters, siding installers.)

I just installed gas heating systems in 2 buildings and we’ve probably had to go into each unit 25 times during the course of the install and the inspections that followed.

Have you considered a metal roof?

Updating the interior is costing me $63,000 for demo, installation, and materials.

Pex is also much easier to install and requires less access. 

Reminder:Ground improvements qualify for bonus depreciation.This includes various landscaping.Roads and external parking areas.Sidewalks and pathways.Fences.Utility systems (including the installation or improvements to water, sewage, drainage, and electrical systems).Outdoor lighting.Rec facilities (like playgrounds, sports courts, and swimming pools).And more.It's a big category for depreciation/bonus depreciation that we love.

It really is not hard to install submeters in most cases.

Tankless WH cost has dropped significantly, they tend to last longer and are less prone to leaks but the initial switch might require upgrading the gas line with potential higher installation price tag.

I have a tenant in Arizona, who moved in a month and a half ago.they keep complaining that the master bedroom is too hot.The whole house is ok but the master bedroom is hot.I offered them a portable ac, they refused took it but did not install.I offered to have a handyman come install it, they said they can do it themselves.I offered the ac guy to come check on the AC and asked them to call the guy, because he likes to schedule with the tenant directly, but they have not called himI asked if they waned me to schedule with the AC guy,- silence.They complain but wont let me schedule for them.I understand that the tenants are just complainers, but I want to cover myself legally.So in case, if they decide to take me to court, I would not be liable.What is the best way to deal with things like that?
