Quote from @Ashley Collins:
@Victor Jernigan it's a 4 bedroom 3 full baths--one bedroom is on the main floor. 2489 sq ft. Fenced in yard, covered patio as well as uncovered patio. It's in West Knoxville--close to where Westland and 140 meet.
Ashley,
There are about 1,500 new class A apartments opening this year along the Pellissippi Pkwy from Hardin Valley to Topside. The average monthly rent for a 3 bedroom 2 bath will be about $2,500. This will cause some downward pressure on single family rentals. Your 4th bedroom is a plus but the 3rd bath is the real bonus. The fenced yard is a positive for small children (no added value) and dog owners ($50 month added value). You can anticipate a long term rental will be in the range of $2,700-$3,200. An equal or better option is for furnished mid-term rental which should be closer to $4,200 per month. Typical management fees in Knoxville are about 8%-12% monthly with some variable fee for leasing. Expect to pay about 20% for mid-term rentals.
Since you made the wise decision to get a 15 year mortgage, ignore any "rule of thumb" you may read on BP or any where else. You are simply paying down debt significantly faster than those who use those calculation.
Also, if possible do not sell. The market in Knoxville is increasing at an increasing rate. The for sale market may not get as high as your husband thinks, but the rental demand will be consistent to increasing for the next 5-7 years.
Good Fortune,
