So if you have a 4 plex where 3 units go for $1500/ea, that's $4500*0.75=$3375 you can count as income to use toward qualifying.$815k is probably well above the FHA limit though in your area so you would need different financing such as an 80%+10% or 80%+15% type of loan.

I wouldn’t count on holding out for a 22% decrease in market values. 

Would simply having the square footage, floorplan/bedroom and bathroom count be sufficient to get a reasonable estimate sight unseen? 

If properties are not personally obligated and it's in business entity, they don't count towards your financed property count. 

Count the daily leads coming in.Add the daily calls that is too much hassle for me right now to do a screenshot and blur out the names and numbers so just believe me when I say, a TON of daily free highly motivated leads... continuously!

As more money comes in, the perceived risk goes down, so people are willing to accept lower returns driving prices up and taking rents along with them.Keep in mind that talking about a city is referring to it at its macro level, and to be successful you have to drill down to the micro level, either neighborhoods or sometimes even blocks.

What about unit count and renovation status for these buildings?

It allows you to diversify not only the door count, but the address as well.

I can't count the number of times we were surveying a property that looks like it has an encroachment based on the record deed, only to have the neighbor bring out a notarized sale agreement that was never recorded simply because they did it themselves without benefit of a survey or legal counsel.

It will be my first deal (unless you count the one I own and live in) I saw you have a goal to find a 3plex and house hack.
