About 80% of the transactions I'm involved with are regular listings.  

Do they interact well with everyone?

I know a student relationship isn't asked below, but it probably should be.Now, I've been on bus tours but with national organizations of government housing officials, pretty dry, but it is good to see and even interact with a neighbor if there is time and you can get away from the tour guide.

Many don't -- and most multi-family projects in most states require an architect's / engineers stamp -- so architects are getting regularly involved.It should also be understood that when working with an architect, developers typically pay the architect for very specific, very partial services on a sort of a la carte basis only.   

I've thought about doing that as I do like the interaction with the guests but it is a job. 

Never bounce a check again :)  Make sure the bank has online interactions because that is the way most people are headed.

But yes, what is the benefit of a HELOC as opposed to just the regular home equity loan for investment purposes?

I use the selling guide on a regular basis to research current or prospective purchases.It might be helpful in clarifying a few points that may contribute to your general misunderstanding.

My husband does appliance/plumbing/boiler/electrical repairs, turns apartments, does inspections, deals with contractors, and troubleshoots on a regular basis.

But I told him it happens in the Hood's of America fairly regularly.
