Hi Nina.If I were not experienced in land lording and property manager, I would look personally to the extent you want to learn or experience property management versus hiring someone else that you trust to do the job.Yes, the cost for a property manager is important but not essential- the cost between property managers are not double or triple the cost of others (say like attorneys in some areas of law or cars). 

Thanks for sharing.

and include my tenant's name and this unknown person? 

Learning about the seller's approach and way of thinking can help you make your negotiation plan more effective.Every seller in the real estate market is different, just like every person is different.

DSCR loans offer alternatives for DTI/income and employment, but generally still have strict personal credit requirements. 

If you decide to entertain this, due diligence will involve digging deep into the business financials to understand cashflow, solvency, and liquidity, his personal finances, and searching for any liens or UCCs in place. 

I recommend buying it under your personal name.

Thanks @Leopoldo Vazquez for sharing the link.

Any insight to the market someone would be willing to share?

When the first type of person chooses to self manage, they generally have a great experience, and they also get to pocket the extra 20ish% that they would pay if they hired someone else to manage their STR.
