. - When I'm shopping for a new location for a client it really mostly comes down to the basics like visibility, is their a lighted entrance, are we on a hard corner. 

The space is 400sqft with a separate entrance, full bath and kitchen. 

Can you segregate the two and have different entrances?

Wondering how likely it is to be able to pull off a Variance, considering the house is a split-level and the ground-floor has its own entrance, bathrooms, windows and everything.

Consider this scenario:-$600,000 purchase price-3.5% down payment ($21,000)-5 bedroom home where you live in one room (preferably an ADU with separate entrance) and rent out other rooms-mortage/PMI/taxes/ insurance= $3,700 a month -if you charge $1,100 per room= $4,400 rental income a month ($4,400-$3,700= $700 profit a month)This is my plan to get started and I plan to do this to 1 new home every year for the next 5 years. 

We have a Nest thermostat to monitor the temperature, a Ring floodlight that covers the entrance door and a digital lock that I can change to code for the door.

I once bought a co op in a building where the sponsors upgraded the entrance way to the building.  

Here are some details that were provided on the proforma - "owner pays gas for unit #4, 5 units have central A/C, and 3 units window A/C belong to tenants.One porch rebuilt, new laundry room door, main entrance door improved, brand new gas line, new fence, entire roof recoated, new drop boxfor rent, some sidewalk segments replaced $2600, 5 toilets replaced, 3 stove and 3 refrigerators replaced, new hot water tank"If you want to be an LP or GP on the deal let me know. 

Every plumbing entrance, soffit, vent, drainpipe, chimney needs to have ¼ inch 23 galvanized stainless mesh sealing.

In Seattle, whenever a service entrance, (i.e. meter box) is altered in any way, it is REQUIRED it be replaced up to present code.
