Hey Matt Rothwell, check out the paragraph that starts (3) Property used by the taxpayer as his principal residence.It's very open-ended, but it's the IRS' definition of a primary residence.http://www.gpo.gov/fdsys/pkg/CFR-2007-title26-vol11/xml/CFR-2007-title26-vol11-sec1-1034-1.xml

Make a sitemap and fine-tune your keywords.

It could take me hours, maybe days to explain each and every one of these.But just to give you an idea how XSitePro2 will help you optimize your website for the search engines, here is a list of tools that come built-in: * Google Map Generator, to create a sitemap specifically to be submitted to Google

As far back as 1996,  the SEC required electronic filing of financial statements through EDGAR , and later adopted XML technology.

Here's a link to their page which has a site map.   

I am trying to build application to pull property information and make decisions based on the data available for the house, neighborhood, properties sold around the same are ect….What is the best fit company/API which can provide API data (XML/Jason) which does the following?

It is usually in a universal common form (CSV, Excel, XML etc.) which makes it easy to port that information to a new service/system.As for how long data stays on the old system, that's something you would have to find out - each service provider may have its own policies.

Also the social share settings, xml sitemap, and robots meta info is run through this.

For those wanting more details, I include financials, pictures, site map, floor plans, maps, info about the market, age of property, # of units, rent and sales comps, return projections, sources and uses, my bio, to name a few...
