Do you have an extra bedroom you can rent out?

I will keep it updated when i have further detail.

Not what you want to hear and I don't have the details on your park so I could be way off base, but if it were me, I'd:-Get the homes up to the standard you envision for the park. 

If you pay for theirs, the rent you charge will probably be higher, which will filter out a lot of tenants before they look at the details of why you're higher. 

@Nate Stitchell reach out to a lender for more details, but you can always use an FHA unless you already have used one.

To give you more detail I own two properties one of them is a condo and the other is a multi-family.

If I can't reach my realtor to discuss the details of a deal, they are useless to me.

Washer and dryer inclusion may get you an extra $25-$50 a month, but you'd have to check what your competitors are offering as many apartments offer in-home and/or on-site laundry.You can also consider LED lighting, pet rent, storage rental as other ways to add value and increase rental income.

I'll send details when I know when/where it can happen consistently.

Let me know details and can get you quotes
