-I am quoted a higher interest rate and more fees since its a rehab loan. 

In case helpful some more info on DSCR loans and how rates and terms are calculated:DSCR loans won't use your income to underwrite the loan.

I want to put in place some incentives for new tenants and want to know if anyone on BiggerPockets has done something similar.Here are a few ideas I have had:First Month Free: Sign a 13-month lease and get your first month freePets: No pet fee for the first 6 months, year, etcRent Discounts: Offer a discounted rent for the first month or two fortenants who sign a pre-lease agreement before a certain date.Waived Fees: Waive application fees, administrative fees, or securitydeposit for tenants who pre-lease.Free Utilities: Offer to cover utilities such as water, electricity,or internet for a certain period for tenants who sign a pre-lease.Upgrade Packages: Provide upgrades or amenities such as free parking,access to a fitness center, or a smart home package for those whopre-lease.Gift Cards or Vouchers: Offer gift cards or vouchers to localbusinesses such as restaurants, cafes, or grocery stores as a signingbonus.Flexible Lease Terms: Offer flexible lease terms, such as shorterlease lengths or the option to renew at the same rate, to incentivizetenants to pre-lease.Refer-a-Friend Program: Encourage current tenants to refer friends orfamily by offering them a reward if their referral signs a pre-leaseagreement.Early Move-In: Allow tenants who pre-lease to move in a few days earlyat no additional cost.Guaranteed Parking: If parking is limited, offer guaranteed parkingspots for tenants who sign a pre-lease agreement.

Purchase price: $375,000 Cash invested: $80,000 Sale price: $605,000 Bought above market rate, held on for 3 years and sold to take out gain for upgraded property.

She estimated we could loan up to 500K on a mortgage with 5% down at a 6.8% interest rate. 

Therefore, I am not sure what's feasible in regards to 1) finding an affordable multi-family out that way and 2) what the unofficial neighborhood ratings would be out that way.I'd appreciate any advice as I consider my options, and a referral or two wouldn't hurt as well.Thanks,Phil

My issue is, I have very low interest rates and do not want to refinance and lost those rates.

If your property was in good location/good condition, i would say yes keep it...you have a low interest rates and i would assume it'll keep appreciating.

Every market is different but check your areas electrical rate history.

Interest rates make it harder!
