What they said.....everyone over the age of 18 has to have a background/credit/ ID verification and sign the lease.

Congrats on your maturity at a such a young age.   

I'm not sure if the program is still going on, but has definitely revitalized a lot of the area when it was once destined to follow the way of other older cities that are aging out of existence both in terms of people and property. 

@Polat CaglayanI've never seen a formula but here is a general rule of thumb for multifamily:The class of an apartment refers to the quality of the building, which can be determined by a number of factors, including age, location, and condition: Class A: These are the highest quality apartments, typically built within the last 15 years.

Be careful not to place your identity in your age/success in RE.

My understanding of Avalara is I still need to input the info so it would take 10-15 minutes to do.

Your referencing effective age vs chronological age. 

Quote from @John Mocker: ChristopherBelow is some info that I posted in the past.

I would like to know more about ways to use OPM  The only way to determine if the home is going to cost you a lot down the road is by determining the age of the mechanical systems & if the structure of the home is sound. 

New occupants will be coming soon, but in a 3 family, i have set of excellent student tenants that renewed.That said, many landlord insurance policies have exclusions for students, so I am trying to gather info on updating a policy to consider the fact that the building is only going to be 33% student occupied.
