Not sure about the need to "be adjoined to my parcel", as in combining the parcel.

While we do allow multiple roommates to set up payments, these payments are processed separately, and aren't combined into a single transaction. 

Current state: Value 240k, 3BR/1.5 BAUpstairs bedrooms are... 1. 10X12 2. 12X12 3. 12x10 A: Add a bedroom downstairs and bath =4BR/2.5BA Total cost = 4kB: Combine the Bedroom 1 and 2 to create a master suite w/ walkin closet and bathroom.

The properties will most likely need to be combined under 1 LLC if they are under 1 mortgage.  

Combining the BRRRR strategy with STR is an interesting concept and something I have explored.I think a big challenge is fining a lender who will refinance a STR.

I would negative on doing this because of its uniques but you have proven its monetary intake.  

We need to come up with about $20k total for closing cost and down payment combined to get in these two cash flowing properties.

If I were to put up the entire $40k my ROI would be around 7%.In your market have you seen $200 cash flow combined with a ROI of at least 10%? 

Then combine that with all the factors of a good rental investment property???...
