You can't really get tied up in attempting to assign a cap rate to a class of property, the cap rate is a function of the use of money, your economic considerations and expected income from the investment.

As a function of your sale you might be helping bump up your comps which could be an added plus.

A  little bit more about the house: it's 1224 sqft, 4 bedroom, 1 bathroom ( very odd and functional obsolescent), there was a rail road 200 yards from house, and  there was an excavating shop/repair company working in the backyard all day long, and house was on the dead end street with rough looking neighborhood.

Credit score is a function of available credit to usage.The algorithm punishes you for using most of your available credit lines.For example take 10,000 a your credit limit.7,500 or more used really hurts your score, 5,000 or more is neutral, and 3,300 or less helps your score.So 75% hurt,50% is okay, 33% or under helps.If CC's are high you can do a combo of paying some down and also asking for a credit limit increase which will lower your balance to usage ratio and should help your score rise some again.No legal advice.
