Being licensed is going to save $ on transactions, give better access and networking which brings deals you wouldn't have caught before, and gives more ways to monetize leads that don't pan out as good buys (can represent them). 

Long Term: Over the long haul, due to  stagnant wage growth, and ever growing supply of "value add" units, and the Federal Reserves insane debt monetization policies - investors will soon realize that they can only squeeze so much rent / RUBS / pet rent / misc. income out of their tenant, especially in areas with relatively low AMI levels.

You will also have to put 25-30% down right now and also cover carrying costs so if your cash reserves are tight I would not recommend borrowing Monet form a bank or hard money lender.

I'd preempt that phone call with some online research about purchase contract assignments and double closing practices in you specific state and then search for someone with a referral to a title company in your area and ask them to provide a warm introduction.As a general rule, you will regret collecting all of your information from a single source and someone offering a one stop shop for all the answers is monetizing you in some way.Additionally, re-framing your mindset from, "I want to wholesale." might prove beneficial.

Option 2 Land lease - if you want to keep the property you can lease the land to someone else and let them develop it or monetize the property.  

I do not buy the argument that you cannot monetize appreciation before asset disposition or refi - cash flow from appreciation is realized through rent increases.

However now that it's generating $300/mo net after property management, etc., and is on auto-pilot, I plan to keep it at least until the tenant moves out. 

I don't need to monetize the basement to make this deal work, but based on the location, it would be great for AirBNB, so I want to find a way. 

I wanted an asset that could provide a convenient vacation option for the family that could also be monetized to reduce the carrying costs.

But I’m sure you know this since you said you’ve already achieved $10k/mo net income.
