Can anyone point me towards a private money lender offering these terms ? 

Here’s a quick breakdown of your options:Option 1: Sell and Buy Cheaper House with CashPros: No mortgage, no interest payments.Cons: Older homes, more repairs, possibly worse neighborhoods.Option 2:Use Proceeds as Down Payment on Better HousePros: Newer, fewer repairs, better neighborhoods.Cons: High mortgage interest rates, higher monthly payments.Option 3: Refinance and Rent Out Mobile HomePros: Rental income, keep property, can still buy another home.Cons:Landlord responsibilities, high refinance interest rates, market fluctuations.Consider market trends, rental demand, and your financial goals.

No debt and credit score is around 750.

Currently, I have an LLC but no insurance. 

I'd suggest looking for one with low-no fees as you're getting started out.

That being said it is a no win situation because even if they accept it I will probably deal with this again with the tenant.

A rental in the B/C class, I would say no.

I called the taxing authority and they said NO.

Lets say someone buys an apartment complex for 6 ml for cash.How much should they add for the closing costs if no loan needed?

@Michael Bishay your biggest challenge will be getting your expected ROI out of Class C & D properties.S8 vouchers aren't necessarily a guaranteed solution.
