Funding for a MHP Fund

Greetings, we are looking for 150K cash for investing in a MHP fund. We received an offer to fund at 4% interest rate and 3.5% loan origination and other fees.

Can anyone tell me if this is, at this time, a good rate and fee? The rate seems good, the fee seems high, at least to me.

Thank you in advance for any information you might have.
