Most of mine are $500 a year or less (replacement costs $140-400K).

When was the roof, HVAC, Hot water heater, windows replaced?

If you finance $93500 that should put you at 55% LTV, replace your initial investment, and leave you a mortgage payment you should be able to cash flow off of. 

I feel sorry for those that have a bunch of Wink products that have to replace them all or pay the freight.https://www.cnet.com/news/smar...

In the jurisdictions that I invest, you have 12 months to replace what was in place as a legal non-confirming building/use.

Now I would like to replace the whole roof of the house.

I want to replace the deck/stairs on the back of my two family.

If you can find a replacement at 100% of rent, maybe it's worth it to cut the tenant loose.

You then have up to 45 days to identify a replacement property and up to 180 days to close on that target.

So, if you planned to own it for 30 years you could be relatively sure that you will replace the:  plumbing, windows, siding, floor joists/piers, and roof (again) . . . that's not touching aesthetic/cosmetic things that will possibly be replaced along the way.
