The upgrade was about 6K.

My short term goal is to make my first purchase, make the necessary upgrades/fixes and find a good tenant to rent my property.

Replace things before they break (proactive) or don't fix what's not broken (reactive)?

Thanks in advance, now to upgrade to a BP Pro 😊

These properties are being offered as a portfolio or on an individual basis, allowing an investor to startegically acquire select assets or gain economics of scale with a portfolio purchase.All assets in the portfolio are uniquely positioned for interior unit upgrades to significantly increase rents and generate high returns.They have undergone 5.7m and 4.7m in recent capital improvements, respectively.

Also if you install them you maybe eligible for insurance discount because you have done an upgrade and provided a safer environment.

You can't let tenants sit around for several days with a broken AC because you are out of the country and can't be reached.4) The difference would be a dollar amount, or whether or not it's a structural repair.

And just now upgraded to Pro.
