Morris invest sounds like a turn key provider, is the PM company Morris invest or is it with a 3rd party?

When I got back to the appraiser should be completely 3rd party and estimate the market value...

No problem with that kind of transaction.But the fact remains that in MA and many other states, wholesalers are not legally able to market properties (or contracts for properties) that they don't own.  

Both will likely give you flexibility to add any addenda you want, while maintaining a baseline of protection and legality. 

Once the property is under contract I am willing to assist with the estimate process with intentions of making the deal happen, this way it’s a win win for all parties.

If the cash was earned legally and you are paying taxes, then just go deposit the money.

My rental property is just being rehabbed and will be ready for tenants in the new year.I've had investment properties for a number of years now, but always rented to family and friends, so this part is new to me.The area is near a university so there are a lot of students looking for accommodations. 

They should not use any third parties, that would just make them a middleman.Try looking at:The Best Types of Markets for Profitable Turnkey PropertiesandWhat to Ask When Working With a Turnkey Provider

I'd spend more of my time understanding the sub-markets of where you plan to move/invest in and track what's going on locally there, then familiarizing yourself with legal processes; maybe even start to make local contacts there prior to your relocation.

Also wondering if I'm taking on any legal risk by participating or not participating?
