Look for listing agents that have a few listings in that area and contact them.

They dont allow you to export, so I pay someone on fiverr to data append in the evening.

(b) Upon relinquishment of the premises under subsection (a) and the acceptance of possession of the real property by the landlord, the tenant shall have ten days to contact the landlord regarding the tenant's intent to remove any personal property remaining on the premises.

I will PM you with his contact info.  

3) how can you evaluate these deals to ensure cash flow with mls data, if possible?

Best place to start would be to contact local installers, who will be able to provide free consultation and put together quotes for you.

and get them to give you the phone contact info of the tax buyer.

A few: Sort of the same with an agent. make contact, See the property, make offer, in writing, include contingencies (sale of your house, approval of all inspections, getting appropriate funding, etc) come to possible agreement on price, have all wanted inspections done (maybe including termite, septic field, sewage lines, etc) read and understand papers possibly from the title company (when I sold mine, I used paperwork provided by the title company).

Since they rely on reviews a lot, you may not have enough data on someone who is new or if you live in an area that isn't well populated.

I'm wondering what I can do to convince the seller when I don't have direct contact to them, and only through my realtor.
