I'm familiar with a DST and a collateralized loan sale (Somewhat makes sense for me to sit and wait for the correction.) 

@Isaac Chun they could offer a promissory note, or cross collateralize other properties.

Not to mention that we live in a world of massive data collection for real estate, your “comps” would be easily red flagged by collateral underwriter programs processing your appraisal.

And save a ton of fees, and have first lien position as collateral. 

Look to put a loan on the paid off properties or use those homes as loan collateral.

After creating an LLC using 2 or 3 of these lots as collateral on a business loan to invest in lets say a single family home to rent out and from there continuing with more single family homes.

That law provides exemptions from enforcement of acceleration clauses including transfers on death and transfers to trusts.I would recommend that you request approval from your lender and expect that most if not all will agree as their collateral is really not being undermined since you are still on the mortgage personally, not the LLC. 

You mitigate that with the underlying collateral.

We are currently flipping another property that we are doing in all cash with an investor so we can't/don't want to use it as collateral. 

If you own any properties (including you primary) and have at least 30% equity you might be able to take out a HELOC (home equity line of credit) by using your property as collateral.
