Commercial BRRRR Strategy?

[Daniel Green]

I've recently been presented with a deal involving four 1/1 houses for one price. My question is this:

If I were to purchase these four properties at one price, would I need to use a commercial loan? And, if so, can I refinance each property individually down the road to get my cash back out?

This is a type of deal I've never really considered, so I'm in very unfamiliar territory. Thanks for the help!
