It can overlap some depending on what the HOA covers since it varies by neighborhood, but I don't think it can ever be the equivalent.

There is a lot of over lap between personal and business.

Another question is "B1 - Real, Residential, Multi-Family" seems similar or overlapping with "B4 - Real, Residential, Four- or More-Family".

I understand, and agree with, the premise of what you are saying, but the broker license honestly overlaps only slightly with what property managers do on a day to day basis.

You both have some fantastic points and I understand that the overlap between tech hubs and cashflow markets is quite minimal (as tech markets tend to be appreciation markets).Here's a harder follow up question that I'm now struggling with: Is it worth forgoing salary/job opportunities to live in a cashflow market (like KC, Indy, etc.)?

There's also very little overlap or guarding of turf here.

If their specialties didn't overlap I think that would be ok, otherwise I would use one.  

Depending on the area you invest (long term rental, short term rental, BRRRR) that list has a lot of overlap and is pretty undisputed.   

The biggest factor in your success will be boots on the ground - meeting people, getting to know a market, building relationships.Another consideration is the MLS you're in - Portland and Corvallis have primarily different MLS's (there is some overlap - but you'll miss a lot in one market or the other). 

You might have some overlap (guests coming and going more often due to staggered rentals) but as long as you meet the 7 days for each booking, you should be good to go.Seeing as you are so close to the beach, a 7 day vacation stay would be pretty normal IMHO.
