Personally I go for multi families in transitioning neighborhoods so I can get a little appreciation as a bonus with the cash flow, but my buy & hold clients (as Max Householder said I'm an investor-friendly agent) have a variety of criteria they use for selecting size (single or multi), condition (turnkey to gut), and geography (South City, North City, North County, etc). 

Equity is a bonus.  

Looks like a really nice place, bonus points for house hacking!

Bonus when world ends you're at least in paradise enjoying what you worked for.. lol I'm not an alarmist but I am a realist.

Now ask your boss to give you $100k-$200k free bonus LOL

We are looking for an Airbnb cleaner (bonus if the person would be interested to do monthly cleaning of our property as well).Also, we are looking for a photographer who could do professional pictures for the property to post on AirBnb. 

And if you find something before their lease expires that is a bonus to them as every month is one less month they have to pay rent.This is a great scenario.

Development potential is a bonus, either by scraping the building, or by building additional units.

Vacancy is the same as tenant placement bonuses to me; loss revenue. 

It's like a shower, you don't get bonus points for having done it, but you do get dinged if you don't.Heat and AC are things that you can conceivably raise the rent for (unless it's market standard that these are already included).
