It is very common for rents to be under market on multi.

The minimum downpayment for a DSCR loan is 15% if you are experienced. 20-25% will be most common. 

Section 8 is a common form of rental assitance in our area, however wait times for tenants to get approved due to demand/limited funding can be significant.

Especially for STR, you could literally put a sofa bed in the living room and accommodate extra guests (before you all scream, this is fairly common even in high end STRs and I've never heard of complaints, but feel free to cite other experiences).

You will need a lawyer.You will need an appraisal.You will need a home inspection.You will need title insurance.You will need a contract with the Seller.You will need some sort of partnership agreement if not a bog standard common law agreement as defined by your state.You will need a survey.You will need to heed the advice of the attorney in whether you need any other documents, and in what any document must provide for.You will need to have in your above documents what happens if you don’t like what is revealed or if there is a failure to get a document.The presence of a real estate agent is irrelevant to those things.Do NOT focus on saving the commission.

As others have mentioned, the common sources are Furnished Finder and Airbnb longer term stays.

You're looking at a 2 bedroom, which I believe is the most common and available for rent there.
