I'm sure someone could query the Zillow servers using their API or by using a web scraper/crawler to determine dates that nearby properties may have recently been rented for.

If you don't find anything local and end up looking on the web check out grant cardone.

First off, as far as "how long did it take for leads to come in" and "how long until you got your first deal from the site" I wouldn't be asking it specific to Lead Propeller customers but to real estate investors in general who are using the web to generate leads.

Also, do you have any kind of web presence?  

Now the information was great but I knew it would lead to more money  that we don't have, so after day one I began searching the web and I stumbled to this site and my eyes opened so wide and I love what I see.A little background, I've worked in the public sector for 30 years, but I cannot retire because Of my age, but I want to do something else and I want to leave our kids a legacy. 

@Shaune Faust  for some very good quick comparisons on one web site from actual providers you can go to Brie's web site turnkey reviews as  @Ayodeji Kuponiyi states.there are Many quality providers in the turn key markets these days.I always like to recommend that1. make sure your buying in good areas 2. searching for the absolute highest return in rental properties ( at least on paper) will many times put you in difficult to manage areas of the cities.3.

Guys - does anybody have a form on the web I can download and fill out (this is a MA rental)?

Do you have signs, a web site, business cards, name tag?

Do a web search.

This could be semantics since my local web site refers to it as the "assessed" or "just value" and not tax assessed.
