But I am hesitant to add one more rental to the market?  

A $200 FB ad done right can generate 100 real leads.

It may sound nice to pay a 5% management fee but the extra fees can add up to be more than the other company that charges 10% with no add-on fees.

Generally speaking, you have a ton of great advice above so I don't have much to add on the str front.I will say that STRs are becoming over-rated and I expect a lot of operators to start performing lower that expected. 

If possible, I suggest house hacking to get started...buy a 2-4 unit with the new 5% down program plus add on a renovation to put icing on the cake!

It may sound nice to pay a 5% management fee but the extra fees can add up to be more than the other company that charges 10% with no add-on fees.

They do have a premium subscription and add-ons that make it more of a property management platform, but I am not using them.

That said, real estate has additional characteristics (cash flow income / value-add on the renovation), it is not mere numerical leverage such as employed in finance.

Instead, you have neglected this core and continue to add on extraneous items (like latchel) that provides little value if the core items are severally lacking. 

I would add one more point.
