I was hoping to query the forums to see if anyone knew of any sites or databases that may show 2/3/4-plexes for sale.

Let's assume you used all of your free queries on your computer, iff you use your smartphone on the cell network, you'll get additional queries for free. 

Hi all,Browsed several posts in this section, but didn't quite get my query answered and would like up-to-date responses. 

This will be the best site for your queries!

Here are a few links that tell about how they form, whom to contact if one impacts you, signs to look out for and more general information.http://www.swfwmd.state.fl.us/hydrology/sinkholes/http://www.plotscan.com/While this next link is specific to Pasco county Florida it gives you a general idea of what to query when looking in your county.

And I suspect you don't work in the war zones or the worse parts of town.I often recommend folks looking for out of state investments to query PM up front as part of the DD phase...

If you want home values of $75,000 to $175,000 with at least 50% equity, then you really can't use a dollar range of equity or you will pay for a lot more data that you do not want.I contacted support at Melissa Data and they said that if I sent them the criteria, they could run the query and give me the results so that was good, but I would rather be able to tweak my parameters and see the counts so that I can quickly tune the results.Also I didn't see any way to get absentee owners that were outside of a certain distance (only in-state and out-of-state owners).I'm going to look at Agent Pro 247 but does anyone have any advise on these?

I think if you do a few queries about marketing campaigns you will find the answers to your questions are already here.  

Suggest you complete your profile along with picture and post your query in a different forum (and  be patient with responses w it hour relying heavily on any). 

Thank you @Wayne Brooks.The thing that queried my interest was seeing closing costs of about 8%.I guess the GFE would spell it all out, if I were to get that far.
