It will require getting higher coverages on your properties but the cost difference won't be significant. 

My brother and I are closing on a home under COA jurisdiction that will require permitting.

I second Bjorn’s comments, but also urge you to learn about your local leasing requirements.

I've owned and lived at the property since 2021 so I meet those requirements.

-Credit Requirements: Ask about their credit requirements to see if you're a match.

Homes will have even more deferred maintenance and tenants will be even harder on them.Class D pretty much requires an OWNER to be on location and at the property 3-4 times/week.

This means they have passed their education requirements, tests, continuing education, background checks, fingerprinting, etc.

I was also happy with that as conventional loans at the time were at about 6%.Lowest rates possible will be in relationships with private money lenders.Lowest rates in the public market will be in the form of a conventional loan.Next up you have commercial mortgages that are usually slightly higher than conventional loans but don't have as strict of loan requirements as conventional loans do.Usually a bit higher in rates are DSCR (debt service credit ratio) lenders.

High cost of entry here, and I have found that most local lenders require 20-30% down with 6 months of reserves for expenses in case of vacancies.

They have to report that on the Federal Depreciation Schedule that is required from year to year on your property anyway.
