You’d require a license for both of those.

@Theresa Harris the ruling require exclusivity to the listing agent’s listings… one just becomes a client of the agent, who you happen to meet at one of their listings.  

My friend has a property but I think he is unsure about the STR regulations/requirement and that's why he is not considering STR arbitrage, but would be open to MTR. 

I also think you should be required to be licensed.

Something like that where you are paying a la cart fees that are applied at close under the buyer-broker agreement and commission agreement.Its going to be fun to figure out this year and next, I’m building basically a subscription based brokerage right now anyways where they sign up for the “plan” that suits them which will require the mandated buyer-broker agreement and commission schedule. 

NV OR  and a few others require licenses to do this.

I don’t think you’ll have a problem selling it as it will be highly desirable for either an investor or a home owner looking to house hack.

I will choose the best comparables to use and then do a market analysis to determine any time adjustments required.

Some may also require 12 month seasoning 

Not care, introduce legislation to bridge mortgage insurance requirements with lack of providers, get in the insurance market themselves?
