After listening to him talk for close to 45 minutes, I finally said that if I have an extra $18,000 to $35,000 wouldn't I just invest that in my own property and get all of the rental income and if I sold the property 100% of the proceeds, not 50% of it. 

If that's not the standard in your area, the potential for the extra rent is attractive.

@Aus Smith if there is base rent and then an extra fee the resident pays for a common utility, we count that as revenue towards a percentage-based management fee. 

Look at the comps in your market, having extra storage is a bonus so as long as it has working electrical I wouldn't spend much time or money on it other than making sure it's clean for showings.

And we’re curious about also potentially installing an EV charger as part of this for an extra perk for guests/tenants. 

The trifecta is making the owner and property manager happy, compensating for the extra risk, issues, and potential repairs, and encouraging the resident to limit the number of pets and be sure they are not damaging the property. 

Also, it is okay to go through some extra maintenance for the short term. 

I'm contemplating this decision because I'm not sure if it would be desirable for tenants to have an extra room instead just a loft area.

We plan to take all extra income after that and pour it into real estate investing.

With this set up, we were able to get a DSCR loan through Kiavi with only a few extra steps compared to an LLC.
