Just like you would do with any non-family contractor working for you:- get them to complete Form W9 for you, as you will need their SSNs- have them provide receipts for materials/supplies and keep those receipts- have a written labor agreement (how much and for what) - pay for materials separately from labor- make all payments electronically rather than cash so you can trace them- pay out of your business account, not personal- issue them 1099s next year if you paid them $600 or more for labor (for the whole year, not per job): https://www.biggerpockets.com/forums/51/topics/1167632-expla... 

In addition to that, most buyers have a preference for placing their own tenants versus inheriting tenants, even if they just moved in.

A very good local agent would be the starting point of the conversation for me personally.

I am currently reviewing the numbers associated with a wraparound mortgage and I need some assistance in determining if they make sense.Can anyone please direct me to the appropriate person who would be able to help me analyze and verify these figures?

I haven’t seen it personally but I imagine it’s some kind of “use us to sell or pay a penalty” clause. 

Did you actually look at these properties in person? 

Come by REI Central some time if you want to meet other investors in person.

It is extremely hard for the average person to afford a standard home, car, and investment property without any debt.

Yes, you can JV with a homebuilder and come up with some type of preferred return and/or waterfall structure to share in the return. 

can you visit them in person?
