Question about how to value a property

[Mark Graham II]

Im looking at a pair of triplexes, one sitting on one lot. The other on the other lot. My question is this: would I be better off treating the deal as separate triplexes? Or as a 6 unit commercial? The owner has stated they don't wish to sell one without the other, and this is something I'm considering approaching the seller with a MLO. Trying to value as commercial has proven to be challenging. There however is value left, all but one of the units rent for a good amount below market rental price. Any advice would be awesome. From what I've looked at the numbers look good, just trying to decide how and if to do the deal
