I figure the ones over 50 or 60 years old have already had all the big ticket items replaced.

We also have different single family and duplex models available.

•Does this sound like a scalable and sustainable business model?

I like using these for just this case.Another item to consider is since this is a 2nd floor I wouldn't be that worried since the 1st floor will heat the 2nd floor enough to not allow frozen pipes.I would also talk to an HVAC person because I believe they can also put a device to cycle the heat a few times a day or even put a secondary thermostat in the apt to take care of the minimum issues.I feel for you because otherwise you have a great tenant.

The list goes on.For mission-critical items, you want quality, not cheap.

Yeah there are several big items! 

The best and most appropriate way to get a value, in my opinion, would be to use a discounted cash flow model.  

Bonus depreciation is just a special part of the US tax code.It allows you to take accelerated depreciation on portions of your property depending on when an asset is put into service.At the time of this writing, you can write off a huge portion (60% in 2024) of many qualified components that have a useful lifespan of 15 years or less.That means a certain percentage of things like landscaping, sidewalks, latches, appliances, fences, certain flooring, etc is depreciable in year 1.The bonus depreciation rate percentage changes yearly depending on the administration and the tax code.For years 2015 through 2017 first-year depreciation for all the items on a 15-year schedule or less was set to 50%.It was scheduled to go down to 40% in 2018 and 30% in 2019 and then 0% in 2020.But then Trump got elected, and he enacted the Tax Cuts and Jobs Act.That moved the bonus depreciation percentage to 100% from 2017 to 2022.In 2023 it went down to 80% and it’s currently at 60%.Depending on who gets elected again, 100% may be back on the table.Only time will tell.We know that the US government wants to incentivize more development and ownership of RE.They want Americans to continue to build and maintain our physical world.That’s why real estate is one of the most tax-advantaged assets in the US.Depreciation and bonus depreciation for RE are very positive and will likely continue in the years ahead.

Since the assumable financing and seller carry combined could put a strain on your monthly expenses, it’s important to model different scenarios for vacancy, maintenance, and management costs.
