Of course the google voice number also adds a layer of protection from Tenants which I prefer.

Cons: 1. 4+ family in NJ is subject to state regulation/inspection/tenant protections.

You as an investor, especially in a sandwich lease may choose to record your memorandum of option or other similar document to protect your interest and potential equity in the property, but you're unlikely to record the option with your tenant buyer. 

Once you find those people, you'll need to have a deal in which they can invest where you can show them how the deal works, how their investment is protected, where their payback + profit comes from, and your exit strategies - yes, plural!

It's also a protection for the tenant as well so the landlord doesn't back out either.

Show us how the deal works, how a lender's money is protected, where the pay-back and profit - yours and the lender's - come from, your exit strategy, and your plans in case "plan A" falls thru.Those two will get you in the door.
