Here are my assumptions:
1. Cost inflation is 3.5% per year
2. Rent increases 3% per year
3. Property appreciates 7.5% per year. (I address appreciation further below)
Current condo situation: 30-yr fixed at 6.875%, monthly P+I of $830.03; monthly taxes at $154.39. About 2.7 years into the 30-year mortgage.
Local mortgage broker has quoted me a refi of 30-yr fixed, 4.88% with a P+I of $613.88, will have enough equity for no PMI.
I believe I can rent the unit for $825/month starting in June.
As to the appreciation issue, our tax re-assessments just came out countywide, with the average county reassessment being 22% increase in value since 2005. Our complex's units are all valued the same, with the value representing a 46% percent increase over 2005. Incidentally, the 2009 valuation is almost exactly what we paid for the unit in 2006. As recently as December, a nearby condo with nearly the exact same floorplan and sq footage sold for $14,000 OVER our 2009 valuation. Zillow pegs our unit at $10,000 over the 2009 valuation. These pieces of data encourage me on the appreciation issue, as does the nearby comparatively recession-proof job base (UNC-Chapel Hill).
So that's the upside. The risks are vacancy, of course, and potential difficulty in raising rents each year by 3%, not to mention a potential tax increase. (though I think a revenue-neutral rate is likely, several county commissioners have already mentioned this as a goal in the newspaper)
MikeOH- I hear what you are saying on rents nationally, but I believe that the local market fundamentals are different here. That said, I readily concede that I do not know HOW different. Any recommendations on how I can learn about local rents beyond rentometer.com?
