Listing, applications/screening, leases, online rent collection, and maintenance tracking? 

@Manuel Martinez Yes presuming ground leases are legal in your state. 

Another option would be to renovate the property and lease it to a commercial customer. 

Even with flips they have failed the septic for non-issues which were eventually corrected on their end but caused further delays.A solution to that could be keeping the power in my LLCs name but enforcing through the lease that failure to pay for electricity will result in a 5-day notice and therefore being ground rules for an eviction.

I personally focus on sandwich lease options which I believe is the best option for short term cash flow.

Maybe your laws state that the tenant has possession until the end of the lease even if they say they have moved and haven't paid.

He does not want a subject to or lease to own. 

One cannot depend entirely on the realtor to know all the details; they are the sales agent, not the business partner.I've met many investors who say the master lease is the tool to use but I have not tried.Last month at a meet up, I found a man who vacationed annually in the Keys at an illegal VRBO.  

I've been seeing a lot of properties with no lease month-to-month (no prior/expired lease) tenants in place (for example, in a basement.

If I get a home under contract with a seller on a lease option market that property find a buyer to agree to a one year lease option.
