If you're planning to sell it and split the profits with the seller, it sounds like you would want a novation agreement. 

At first it sounds like typical, corny corporate-speak: PM business is relationships, not transactional.

Yes.It sounds like you could use professional assistance, but it would be nice if you could get the guidance for free.Airbnb pays "Airbnb SuperHost Ambassadors" to guide and advise new Hosts, with no cost to the new Host.  

Sounds like a solid plan starting with wholesaling.

Sounds like you're doing the right thing.

@Steven Rosenfeld, I am hoping to provide a little more color here.It sounds like what you are wanting are "vertically integrated" operators, like BAM.  

Sounds like selected the wrong management company that was gun shy and cost you a lot of money.

You bought it as a primary and kept it to start investing, but that doesn't sound like a good investment and HOA can keep going up or there can be assessments and your appreciation is much lower in a condo than a single-family.

STR is definitely not a rookie game right now, but your flow to success you have sounds way easier than it is in real life.

As noted above by Chris, they'll be able to help with the offer process and provide a sound purchase and sale agreement for use.
