@Bob Langworthy thanks for your reply. I'm going to have to look into this more in depth, just not sure where or how to get all the answers. I responded below.
1) Why has it been empty for so long? - an elderly couple was running the 2 businesses themselves. it became overwhelming for them and they couldn't keep staff regularly, people kept calling in sick and they started taking on the bulk of the work. they've owned the businesses for 20 years and are now ready to retire.
2) Any deferred maintenance? there's some, but the building looks like it's in decent condition. nothing obviously in poor condition.
3) Do you have any prospective tenants? no, but i want to contact the corporate offices/brokers for the same companies that were in the spaces and gauge their interest. if not, then i'll go to their competitors in the same space.
4) Is there the possibility of seller financing? i haven't asked. not sure how to have it structured? they're ready to retire & want to buy a motel & run that instead of the 2 businesses. they mentioned wanting cash, but I didn't propose owner financing. how would the realtor get paid in that situation? she may dissuade them from that option.
5) What have similar properties sold for in the area? i'm not even sure how to research this. should i call a local retail broker to find out?
6) What are similar spaces leasing for? not sure again. i'd have to find out
7) Have you developed pro forma financial statements and if so,what are you assumptions based on? no
