It does not appear that many newbies (or experienced) investors are buying much (transaction levels are at record lows). 

Quote from @Jay Fayz: Hello everyone,I've recently been exploring real estate as a potential career path and I'm looking for advice on the best entry-level job to gain experience and knowledge.

Right now I own a duplex, I live in one unit and rent the other for $1400 per month.

Either way, after five years, I can say I achieved a certain level of passive income—just not the kind that puts cash in my pocket. 

Good points.I'd add square, level, plumb - license, insurance, bond - using permits to follow codepointing out problems the owner doesn't realize they have that are serious. 

House hacks are fairly straightforward regardless if the units are separately metered.

I would look at the DSCR loan as the first option.By the way, I suspect you are going to be disappointed by any refi appraisals   ADUs typically appraise poorly   JADUs can lower the property value Vs having the space as part of the primary unit.  

Hey everyone,I’m looking to level up the welcome basket I provide for guests.

The biggest things for our energy bills are: how many ac units are on the house and do you have a hot tub.

Investment Info:Large multi-family (5+ units) commercial investment investment.
