Tax abatement ends in 3 years...will reduce cash flow

[Hayden A.]

Hi all. I'm looking at a 3-unit apartment building. It's 2.5 years old with a tax abatement that ends on 12/31/26. It will cash flow very nicely until then. i spoke with the city assessor who told me that if it did not have an abatement, the tax now would be $19,000. I think it will be at least $20,000 by 2027. This will greatly reduce the cash flow to a point where it's not too appealing, even with a higher gradual rent increase by then. however assuming with continued 3% rent growth per year, it will eventually cash flow nicely again 2-4 years after the tax starts, assuming rents and expenses all grow at 3%.

What do you think? am i missing anything? should i skip in the hopes of finding something better than will always cash flow nicely? it is extremely hard to find good deals in my market. 

side question: given that this is a big 3-unit apartment building in a HCL area, how much should i set aside for repairs, maintenance, and capex every month/year?
