EDIT:
Post #35: I find the opposite. Don't have to get nothing-don't already have in the Toolbox. Countless Agents are aware the property will not make 10 days on market & just need accurate data for the listing.
YOU SHOULD! I provided measuring services & stacks of business cards. A (southpark) Broker chose me-preferred me-referred me to measure
all agents listings, then it multiplied X' s. Good $$$, very quick. Back Then: Trip Local $25 + hour wage. Two-Type Service: GLA sketch or GLA with interior sketch. Option: all exterior improvements. Of course, some were "not fun".
Appraising was my path, I didn't stick with it AND should have been smarter to have a second business by training mini-me's

Good Memory: Met so many interesting people, some snobs some not. A few were bank-influencers, quite well-known & very kind. One was college-pro ball famous & his Mom requested I stay for dinner. LOL, almost did!
