I can't speak for others so it will be interesting to hear their take.

Looking for some info as far as deal quality and things to watch out for.Price: 149,900Units: 12More info:9 lots occupied. 8 of which are park owned.3 vacant lots and room to add 4 more.Ad claims 42,000 a year in gross income currently (with the 9 occupied units).I believe that makes rent/fees income equal to $500/month per unit.Wondering what sort of stuff to be wary of when reading ads like this.

@Luis Barberi I would highly recommend you look into due diligence groups like @Ian Ippolito group.Ian can speak much more intelligently about it but I would google The Real Estate Crowdfunding Review and the 506investor group. 

Air quality of your property is important. 

Speak to a CPA about that, but depending on your specific facts and circumstances, it may not be necessary.

Should I speak with an attorney before hand? 

The new contractor may discover quality/installation issues from the previous contractor. 

CoStar and other companies mentioned are trying to increase the volume / quality of data but even then this is a very fragmented industry.

From what I've experienced with LLC financing, if it's a newer one (less than 2 years old), they'll underwrite your personal finances, but I've received different answers from different lenders so you'll have to get direct answers from lenders you speak with.

What they are speaking of is the tax advantages for me.
