Been trying multiple sites or softwares like dealio, crexi, zillow  in finding the best deals.

You want an accountant who can help you strategize and who is responsive when you want to know the consequences of the financial decisions you are making throughout the year.There are over 20 real estate accountants on this site.

Quote from @Dave Skow: @James McGovern- most lenders can get underwriting done  that fast  as long as they are provided with 100% of the data they need PLUS getting any disclosures needed signed immediately too  Where on the lender sites do they disclose the information they need?

Developed by Icade Promotion and Groupe Duval, the site is already 90% leased just months after completion, with tenants like Nocibé, a French cosmetics distributor, leading the charge.

I'm new to this site.

I look up the seller's name on the appraiser's web site and then run it on the Clerk's web site to see how many transactions he has done before. 

Full disclosure I’ve only recently acquired a few properties so I don’t have years of experience I just know that when I was making my decisions on where to invest I did use that site, but not exclusively. 

The costs of land  , engineering , site work , permits , labor , and building materials make this virtually impossible . then there are zoning issues and the rest of the politics that go along with this . 

You need to run through a few of these sites and see which one works best for you.
