Weigh the long-term benefits of the low mortgage rate you have versus selling and getting $500k from a sale exempt from capital gains tax.

Credit is a factor as bad credit may limit options, or may have the lender require you to put 10 or 20 years of taxes and insurance into escrow. 

I'm sure over time more laws will be created to force the government to give that information in a more timely manner but for now they often obstruct the public by withholding it for a time.

Quote from @Michael Smythe: Besides MANY self-labeled "gurus" exaggerating their success, many of them just supply readily available info.If you're too busy to find the info and are willing to pay for it, no problem as you accept their time vs money solution.REGARDING S8 GURU ISSUES SPECIFICALLYMost of them don't share all the facts about how Section 8 actually works.They claim you can get HIGHER rent from S8 tenants vs private-paying tenants.Why would the government allow our tax dollars to be spent this way?
