Generally, dealers loan money when a buyer has a piece of land to include as collateral.

The IRS will look at ‘investment intent’ and will call a taxpayer quickly flipping property a ‘dealer’ vs. an ‘investor’.Best bet is to consult with your tax advisor

Thanks @Jonathan R McLaughlin, @Matthew Irish-Jones, and @Corey M. for your replies and insight.

If the IRS determines that your intent all along was to sell, they will label you a dealer (at least for that transaction), and the property will be considered inventory, not an investment.

Also ALL dealer properties don't qualify, that would include flips, wholesale deals, builder properties etc.If you bought a property today and 1031ed it tomorrow, the argument could be made that the property was NOT an investment property. 

With a Lonnie Dealer I have to worry about constant tenant turnover and as a result have to be involved in the screening to make sure they meet my standards (as Jay mentioned) - in line with the other tenants.  

Take the candidate(s) that are the best qualified and best meet your screening requirements.A coke dealer could possibly pay a few years upfront rent...but do you want to rent to them just based on that !!

Youtube might be mankinds greatest invention. This gentleman has 7000 doors in the Boston area. Check this video of his first property and how he got the bad tenants to vacate in 30 days after his purchase. Would you ...

You may want to call a few mobile home parks and/or mobile home dealers who have done this in the past.

So, stop listening to gurus, wheeler dealer investors or those that lack basic business knowledge. :)
