I’ve also heard about the possibility of buying a new property with a lower down payment while keeping my first home as a rental.

In the past, the Department of HUD targeted S8 rents to be at the lower end of a rental market.

The longer the term, the the borrower's ability to pay and the more stable the payment history, the lower you can price the earned interest rate on the note. 

If you're considering scaling your portfolio, what loan features matter most to you – lower interest rates, flexible terms, or higher loan-to-value ratios?

Is your rent cost lower than the average in your area due to leaving the utility cost with the renter?

Refinancing out of this interest rate to a lower one could be difficult currently but its a potential option in the future months.

While buying near a hospital can sometimes be a good investment, in this case, the hospital in question is MetroHealth, which is a county hospital primarily serving lower-income residents, many of whom are on Medicare or may not have insurance.

I love to see the debt lowered every month with principle payments.

Thats why I was considering markets which might have lower barrier to entry probably capped at about 300k 

Now I know this isn't an apples-to-apples comparison but to me I would seem to think that Class A properties would have a lower cap than a C+ value add property.
