Ended up calling the Jersey City Division of Housing Preservation and in essence the entire home has to be in good order even if certain parts aren't accessible to guests.

Also, check local zoning and park rules to ensure flexibility with different housing types.

It's a 3 bedroom house and we plan to use technology such as a smart lock, WIFI exterior cameras, and a smart thermostat.

But to answer your question, House canary is good for rent rates, zillow is a good tool for property data and for seeing what is for rent for how much, sales comps etc. 

I am considering buying a property in Spokane that includes two separate housing units. 

Congrats and I would recommend join a team or find a popular brokerage where can host other agents open houses to meet clients.

House hacking and multi-family properties are great ways to start in real estate!

What would you do in my shoes I don’t invest there so take this with a slight grain of salt but I’ve heard multiple stories of basically this exact scenario someone getting offered a big payday for something in Cumberland, rejecting it & always for some reason (house burned down, block got worse, sheetz decided they actually didn’t want someone’s land for a car wash after all) always selling for like 10-20k and regretting not selling. 

About 2 years ago I bought a house near the ocean, which had a barrel-tile roof.

I saw that the population grew by 5% from 2020 and I haven't seen much development as far as new housing goes so what could be causing this uptick in time on market?
