I think it's ironic that Fannie Mae was bailed out by the federal government because of its incompetent underwriting yet you assume this one will work out. 

Some just make perpetual threatening phone calls.Some start court actions, so they get a money judgment which they can use to at least garnish state income taxes (you can't garnish federal returns).Property owners need to start asking PMCs HOW they will execute their services, so owner expectations can be better met:)

Other loans like FHA have a federal requirement.Do you know what type of loan you would like to use?

More details:Mortgage (principal + interest): $2930/moProperty taxes: $15K/yearHome insurance: ~$1K/yrCost of home ownership/month: $4280/yr (not counting for any tax deductions related to the interest and property tax)If I account for $20K of interest and $10K of property taxes as an income deduction, then I can reduce the cost by ($30K x 35%) divided by 12 = $875 per month = $3400/mo cost of owning the houseRental income after 35% federal income tax + 9.3% state income tax = $2618/month (!!)

An unrecorded "lien" is not a lien regardless of what someone in the government tells you.I suggested a few posts ago that the bill (not lien) in question may have been so old that is was off the radar of everyone involved with this property for years. 

You can check on this with the governing fire department for the property.
