it's the return on their investment.  

I'm a number cruncher as well,  I always like to measure Cash on Cash Return, that's my fav number :) What is your key metric?

I was thinking about selling it and buying other rental properties elsewhere, where I could get a higher rate of return.

What COC returns are you trying to hit before you pull the trigger?

I get a snotty return text (at least that's how I read it as you can't really read a time in a text) essentially saying they hadn't received the unemployment check yet for the last two weeks of August and since I wouldn't let them make payments and wanted payment in full . . .  

I have started speaking with folks who do rentals >30 days in the East Bay and South Bay, and they are generally getting returns well above long-term unfurnished rentals. 

The NPV is the Net Present Value of an income stream, discounted to the cost of capital (or required rate of return) and the IRR sets the NPV function = 0 to get a rate of return.
