You can use the remaining debt and all of the other cash flows to compute an IRR at each cash flow.What is it that you are trying to do?

Life is too short to deal with people who are irrational.

This means an IRR at 20% or higher at the asset level.

But we can calculate ROI during any period (year) or cumulatively over the lifetime of an investment, and the geometric rate of return will equal the IRR at the end of the investment. 

.* Painting: unless you are so busy you literally don't have time to do this or you hate it with an absolute and irrational passion then you love throwing money away.

In Ohio, does anyone know if you can have a "Irrational Tenant" Clause in your lease?

Or is that just being too irrational?

Hi Jay,We target a 17%+ IRR at the investor level and 20%+ at the deal level.

However, I'm afraid it could bait good tenants into leaving early, especially in the winter months (probably an irrational fear).

They just irrationally and reflexively recoil at the words rent control, like the word socialism.The biggest and most famous rent control city, Nyc, has the biggest, largest number of mega rich landlords.
