One thing I would add here is to check prior landlord references, not just from their current one.

Most cities don’t want a mobile home park in their city limits because the tenants take more money out of the tax system than they contribute.

The first thing prior to this would be to verify this is a good tenant, check the lease, and confirm with the owner with a payment ledger that they have been paying on time since they have been there. 

Is your DSCR ratio greater than 1-meaning are you cash flowing (according to the lender's criteria of mortgage, property taxes and insurance (and HOA) if applicable).

NC is a great market for your goals, however it will be challenging to find inventory that has much cash flow; many people who toss money into multifamily here do it to avoid the tax bill + take the 10 year runway of growth.How much SHF RE do you currently have?

The homeowner has direct title, can sell at any time and gets 100% of the appreciation and tax benefits on these houses.

He isn't a motivated seller.If it will rent for $1900  a month, that means to make money you have to have a payment that includes, principal, interest, prop taxes, insurance, at less than $1400 a month. $190,000 at 3% interest is P&I $801 + prop tax plus insurance a month.

Currently, interest rates, taxes, and insurance are very high, making it difficult to cashflow with downpayments that are below 40%.

You filed two full year tax cycles and the numbers are similar (no greater variant than 1%) they maybe yes.Generally depreciation is added back as income BUT only the 40% portion you own not all of it.

I had constant issues with the local government and the taxes were absurd.
