My firm, Brown Harris Stevens, has a deep national and international sphere with thousands of affiliates- let me know if you'd like me to connect you to our partners in Washington State.I studied Hotel & Restaurant Management in college- I recommend taking the total # of keys (rooms) in the hotel, multiply by 365, which leads you to the maximum number of stays per year, and find out the average cost per night, and the average rack rate (highest price someone is willing to pay) for the hotel.

I've always heard it called GRM (gross rent multiplier) and I've seen it done 2 ways, like Chris price/monthly rent or, if you ever see significantly lower numbers, then price/annual rent.

So your math was almost right, just need to multiply by 100 to get %. 

MFH multiplies your management responsibility; what you gain by having one roof and one location you subtract by being involved with interpersonal relationships, as there will always be instances of tenants not getting along, ruining the atmosphere for everyone else, etc. 

Pricing additions such as:  Single family no add, 2 units .25 3-4 units .5 ; non owner occupied .75; FICO 680-699 .25 ; each percentage point is multiplied by loan amount.You can pay these in cash or increase the interest rate to cover..125 in rate equals .75 in add depending on product typeThe loan level pricing adds are additional costs for items that the secondary market (who loan is sold to) or the lender appetite for risk.Rates have been volatile.

I give them kudos about being relatively early on the scene, though it seems like options are multiplying.

On an MLS, if the gross rent multiplier is listed at zero, it could be the data was not entered, that the property is not rented or the information is not known....that's my guess.

Are their any benefits in creating multiply LLC's for this purpose?

My opinion: keep that loan in place and multiply the cash flow into more deals.
