Multifamily - 8 Units

[Angel Meraz]

I've only invested in properties of 4 units or less. I'm exploring an opportunity to buy an 8-unit complex and was wondering about the cash-out refinancing and how the banks determine the value of the property. I've read that for commercial properties, they use the cap rate method to calculate it and to a lesser extent, comps. is this accurate? Also, what is the typical LTV % for these type? thanks.
