When you hire a licensed professional, you’re looking for two things - expertise and legal protection.You mentioned researching the market, finding comps, reviewing disclosures, etc...Each of these steps comes with nuances and, in my opinion, takes a ton of experience to master.

Looking forward to your insights! 

This is because those who househacked actually pulled the trigger and started to gain experience while those looking for strictly an investment were too focused on numbers and returns to get their hand and feet wet.You can put little money down and take advantage of favorable rates. its a no brainer IMO 

@Blair Ross Jr I tried this "new" thing called Google and look what I found:https://www.michigan.gov/lara/bureau-list/bcc/sections/mobil...

I'm looking to exchange a multi-use property I own in the Bay Area for a multifamily property in Phoenix (looking at 15-19 units).

well you dont say how much you have in it.. but if you can sell now and lose 10k and get out of a HML that would be my suggestion.HML  if they go into default interest and you could look at losing quite a bit especially if your HML is one of those that are not forgiving and wont give an inch on what they are owed.

This amounts to lost opportunity because if you had purchased RE, at the closing it can start producing return. 5) ADUs detract from the existing structure whether this is privacy, a garage, or just yard space. 6) this is related to number 1, but there are many more buyers looking to purchase homes for their family than there are RE investors looking to purchase small unit count properties.

Look at their marketing strategy.

Are you looking to tap into your equity via a HELOC or Refi? 

@Caleb Genry I'm looking for a easy to use spreadsheet as well.
