@Mary M. @Lewis A Martinez , I don't think this is the best way to look at this. What Lewis paid for the house is a sunk cost...so don't use that to calculate IRR (or anything). Instead, think about the equity you have in the house right now. $80,000. What could it be doing for you if you put it into another asset?
Right now it's costing you $9k a year...but earning you roughly $9k a year in amortization.
So all your gains will mainly come down to appreciation (I'm ignoring depreciation)...like all real estate, that is by and large local. Austin prices just flatlined during the 2008 recession. I'm guessing since your house dropped so much in value maybe it's location doesn't have as good fundamentals (population growth, job diversity, etc.) ??
And remember, your returns will be levered. So if the house goes up 10% (or $24k), your return will actually be more like 30%...since that's your equity growing from $80k to $104k. (The opposite is true as well...if the house drops by 33% you'll lose all your equity...$80k).
Hopefully that makes sense.
