It’s a low income neighborhood with lots of development going on with non-profit organizations (Habit for humanity and Metonia) for the income range your looking for.  

I would mention the fact that your neighbors are ok with your renovation and that the administrative nightmare is causing you and your family financial harm. 

SOOO many of you come here with mere opinion, and what they are telling you makes ZERO sense, so many of you are failing misserably at this... and NO ONE questions those opinions and everyone readily accepts them, votes for them and tries them...Then someone comes along with actual proof and logic, intelligence and common sense.. and HE gets the doubt, the skeptism, the resistance, the challenging remarks and the disbelieve.It is truly fascinating to me.People make decisions based on emotion, ego, stubbornness  and habit... not on facts, data, evidence, or intelligence. 

If you want to lower your DTI there’s no harm in that, but don’t over-leverage yourself.

Commercial apartments have become increasingly harder to insure with many carrier freezing that product line and or taking huge rate increases for habitational products.

You want the tenants to be in the habit of receiving a rent increase of some sort on every new lease.

Thanks.No, you must maintain a habitable space for the tenant until they are gone regardless of the cost to you.

Every time I’ve treated these people with professionalism, honesty, fairness and never let it get personal to the point where they would want to bring me personal harm.

We don’t know any PMCs to recommend in the area mentioned, but since selecting the wrong PMC is usually more harmful than selecting a bad tenant, you might want to read our series about “How to Screen a PMC Better than a Tenant”:https://www.biggerpockets.com/member-blogs/3094/91877-how-to-screen-a-pmc-better-than-a-tenant-part-1-services-and-processesWe recommend you get management contracts from several PMCs and compare the services they cover and, more importantly, what they each DO NOT cover.

It does involve "habitation" though even if you don't own the mobile home itself and that is enough of a reminder for me to stay in my lane:)I have carved out a little niche purchasing timeshares at foreclosure and then renting them out and/or selling them for a profit.
