I’m working on developing my own list of questions but I’d love to hear other opinions.

I do plan on having a proper office and hire a few employees (3-5).

It was newly built in 1987, the developer got a mortgage of $300K, based on appraisals of $350K.

I spend a lot of time reading and listening to develop them. 

If you dont have a bookkeeper, it is your duty to properly track all the income and expense so that the income can be allocated to each property and eventually to each state. 

I guess my main reason for holding back is not knowing how to properly assess deals and crunch the numbers.

I always allow for 3-5 days of vacancy because I need time to properly inspect, arrange for cleaning and repairs, etc.

Usually tenants like that will not properly care for the unit, so I would make sure you will be able to cover the cost of turning over the property. 

Have rental increases of at least 2% go up annually each year.If you are building from the ground up and are not experienced have a fee developer help out but they can cost 100k or so per project.You could also not even construct the building but have the tenant do a ground lease instead.

@Kai Van Leuven developers developers developers developers developers.I have no idea what people are doing in the city of Seattle w.r.t. rental property, but it feels like every house that isn't an owner residence is immediately bulldozed and replaced with a mcmansion.
