Some of the info Im looking to find is for my local area MD/PG County area is:-Market inventory-Avg days on the market-Median sale price-Forclosure rates I've read some of this info if not all is collected by the local board of realtors & released to the public quarterly/monthly.

As a result, we now have three new "vulnerable renter" ordinances that will trump state law, they extend the notice period for both no-cause vacate and rent increase.

REOs might not be available as such on ANY site unless the lender has released them to their listing agent for sale / disposition or the bank is itself selling them thru Hubzu, Auction.com or some other outlet.

If you know of specific subs or suppliers for the property, insist on Final Releases from them.  

If it's a dwelling structure of 6 or fewer units, the initial redemption period is 2.5 years and can be extended by the tax buyer to 3 years.

Last time I checked the seasoning period was 1 year on Fannie/Freddie loans but it has been a few years.When I ran into this situation in the past I explained what I was trying to do with my hard money lender and encouraged him to extend his typically 12 month loan out an extra month or two so I could refinance based on appraised value.

@Matt M.say there is a $100k house3% fee for assignmentYou can list the home with a sales license as a lease with option listing, $3000 down as option fee OR use an option release as a principal buyerI use an option release fee not an assignment feeSay market rent is $1000 So I'll lease for $1000 and have an option fee for $100Then record my optionI want a buyer to step into my contract for an "option release fee" of $3000I'll have my RMLO and credit improvement specialist look at credit and ability to repay of buyerThen an option release fee is paid to title co or attorney or broker of $3000Once $2000 of first and first and last months rent cut to landlord from buyer to closing agent and $3000 is paid to closing agent, then I cancel my lease and option and write a new lease and option between tenant and seller.

This would extend your lease and give you time to make a decision...including, getting yourself into a position to buy it.  

However I have never heard of the IRS foreclosing on their lien.A Lawyer told me to just hold the property and rent it for 10 years or longer.Other option is to see if IRS will release lien since they are trying to get money from previous owner who no longer owns property once you are deeded property.

Talk to the long-term tenant and see if she plans to extend/renew.
