Hi @Krysten Zarembski!
This is a really good question and one I was asking a year ago when I decided to jump into the MTR business. My conclusion then was this: if an investment pencils as cash flow breakeven or a small positive cash flow, using conservative underwriting assumptions, it would be worthwhile to buy despite the high interest rates.
Real estate investing has three main sources of wealth building: cash flow, appreciation, and tax benefits. So I figured that if I could avoid negative cash flow, the other two sources would carry us until rates declined and we could refinance to lower interest expenses. Lower expenses means higher cash flow. Furthermore, if rents rise in the coming months/years, this too would increase cash flow.
When underwriting, I did not use these positive assumptions about declining rates or growing rents. It needed to be at least cash flow neutral to meet our "buy" requirements.
One year later our thesis is working. Our net operating income (NOI) margin is 54%. After subtracting interest expenses from NOI, our cash flow margin is only 7.4%. But it's positive!
With a half point rate reduction by the Fed, our HELOC rate was reduced by the same amount, and we've begun the refinance process. The property appraisal came in at a 5.3% increase versus our purchase price.
On tax benefits, last year we had a tax loss on our MTR business that lowered our personal taxes by an amount equal to 20.8% of our MTR gross rental income. In other words, this is cash we didn't need to spend (to pay taxes) due to our MTRs.
Taken together, cash flow of 7.4%, appreciation of 5.3%, and tax benefits of 20.8% is a promising start for us. The tax benefits have been the largest source for cash income so far; in future years this will likely be lower because much of our tax savings has been due to one-time costs related to purchasing and furnishing a new property. Depreciation will continue to provide tax savings for years to come, of course.
Appreciation isn't cash earnings, of course, until the property is sold, but it does factor into the overall wealth building opportunity in real estate investing. And it grows tax free.
I hope this is helpful to you, Krysten, as you figure out how to proceed. I recommend Real Estate Rookie by Ashley Kehr; she covers these topics better than I've done here. For MTRs specifically, I recommend 30-Day Stay by Zeona McIntyre and Sarah Weaver; they helped us run a lean operation. Both are published by BiggerPockets.
All the best!
