In my understanding, a lease option I can essentially charge more for rent, not deal wih property management because that’s now the tenants responsibility with an option to buy, and so on.

My first deal was for a 225k house that was in terrible shape; conventional financing wasn’t possible, so Seller had to have an all cash buyer or come TO TERMS with acting as the financier... 

No because they charge for the costs of advertising when they find a tenant, so you would be paying all of them or if they are aware they will all rush to put a tenant in the property which may not be qualified.

I'm a wondering if they'll eventually start charging for their service, but we'll deal with that when the time comes. 

For 20% down 30 year conventional loan it is 4.63%.

Specifically, I will be charging for tenant placement and a monthly management fee.

DO NOT let them charge termination fees or other penalties for terminating management.

The problem is the amount of conventional loans that an individual can have is limited.

Those fees charged to me.
