@Kay S.Assuming you are getting title insurance (which I recommend) the closing costs will be similar to a traditional closing.

You can refinance into more traditional loans later, but that initial speed matters.

They provide flexibility and efficiency, especially for experienced investors.How have you found the terms and structure compared to traditional options?

The "slow flip" I am referring to was purchase the property in the traditional financing way and then live there while rehabbing and improving (adding bedrooms, getting the yards back in shape, updating finishes, building or adding shop space, etc.).

The mortgage company gets paid off first, then in a traditional sale, the rest minus agent fees and utilities and closing costs goes to the seller.

If the houses are in decent shape and could get traditional financing do not sell seller finance.

@Rafael Ro Traditionally, investors have targeted Class B properties. 

Unlike traditional banks, which focus heavily on personal credit and income, portfolio lenders prioritize the cash flow of your property.

This may provide you with lower down payment options and more favorable terms.No Documentation Loans:While traditional no documentation loans are rare, exploring private lenders or hard money lenders might offer alternative financing options.

Because they aren't traditional tenants in the sense with a 1 year lease and to determine fit for the house, I like to start everyone on 2-4 month leases and see how they perform.
