The one guy I spoke with said they make money only when they sell to potential investors and they only sell new construction homes that are usually pre-leased to buyers (currently they are building in Texas state and Missouri State).

You need lease and deposit check at closing so the property has to be move in ready not a rehab.

You should get these things for all applicants:1. rental application with employment reference and personal reference2. credit3. past landlord reference4. check for eviction historyMost apps like RentSpree include all this in what the tenant pays to send you a report.I cosigned for my daughter and her boyfriend on their first lease.

And the NNN leaves you only managing a long term lease rather than managing a property.And given your expertise, there's nothing wrong with a transition from farmer to landlord of the farmer. 

Politely and clearly, make it extra clear that all information will be verified including income prior to the signing of any lease.  

If you don’t mind moving somewhat frequently this is a great way to start your portfolio.

I would caution you not to necessarily expect your NOI to be higher because you achieve higher rents leasing units to Section 8 tenants.

The only thing I'd add is to do an 18 months lease or so, so that when the next lease is up you'll be in the warmer months. 

If I secure renters and show a lease agreement and deposit can I get into lower interest rate mortgage?
