We were exploring taking out a primary mortgage on their home to take out 350k in cash at about a 6% interest rate, and I take out a loan from them at an equal rate or slightly higher (maybe 6.5%).

I'm currently doing 3 month trial leases and if they feel it's a good fit, they can extend to a longer term lease or do a month to month and a higher rate.

I’m happy to use any resource with better rates to finance our properties.

With interest rates, home prices, and rent prices in my market to hit that goal of $500 per month I am looking at purchasing a house around $200K, putting down $100K, and renting it out for around $1,500 per month. 

Are there websites that will give me the current rental rates for 2, 3, or 4-bedroom units in the different parts of Baltimore City, Maryland?

One has a 10.25% rate and I don't plan to sell for awhile. 

We went back to the appraiser for re-evaluation and they even exceeded the appraised rent rates we needed ($8500/month).

Condotels are more difficult to get financed and typically come with higher interest rates. 

Sellers will still be allowed to pay a buyers broker although not advertised o the MLS. 

Back in 2015/2016 you could find a 8% cap rate then in 2017/2018 it was a 7% and 2019/2020 it was 6% and the only reason it has been steady is because rents have seen increases along with pricesSo I tell my clients they have a few options:Buy now on cap rate and refi when rates go down.
