In my market you can get an additional unit for each affordable rent unit.  

If you dont have the issue on your list add it.  

I would greatly appreciate your input on this matter.Here is my setupPurchased property under a TrustLLC in FL owns the TrustHolding company LLC in WY owns LLC in FLI purchased the property sub-to, took over the seller's mortgage and I’m working on setting up insurance for the property.I understand I need to keep the seller as additionally insured in my insurance, but the seller no longer has "interest" (ownership) either in the Trust, nor any of the LLCs nor in the Deed nor Settlement Statement.

Get detailed quotes on these to ensure it’s cost-effective.Zoning & Permits: Verify that your current property allows additional homes and meets zoning requirements for multiple units.Rental Demand & ROI: Assess demand for singlewide rentals in your area to confirm it’ll be profitable after all expenses.If everything checks out, these could be solid additions to your portfolio.

@Anthony Britto Additional Dwelling Units are now by right in RI.

Go to Etsy and search for "rental property tracker," and you will find hundreds of nice spreadsheets to track 10-20 rentals, usually for under $10.Software has extremely helpful features like online payments, marketing syndication (click a button, and your property is advertised on multiple sites), electronic document review/signing, maintenance tracking, and owner reports.

Now that I'm ready to rent two additional units, I feel I already understand the software.

@Nold R.In addition to the great post from Dave, possibly consider an option where the property is taken out of the LLC sooner rather than later and held as tenants-in-common prior to the sale, possibly setting you up in a position to take your share of the proceeds and individually purchase a replacement property via 1031 exchange. 

It's an investment into the property, and if/when they move out or even if they're there you can now add a traditional dryer to the property and collect additional rent.

(Still awaiting Seller to confirm report it’s been done as she agreed to the inspectors recommendation but has mentioned she’s not replacing it) In additional to the foundation has shifted and need reconstructed due to a lot of slopping in the home (My agent said it comes with wear and tear, so they might argue that their not going to fix it so I didn’t put it on the IRSA to repair).
