I agree with Account Closed, I think you'd be hard pressed to find a 2-4 unit in an A/B neighborhood in Sacramento for under $400k without needing extensive renovations.

In fact, I can turn my TV on almost any late night of the week and find the next "great real estate system" that will make me rich, after I'm lured in by a "free" information seminar only to have to spend tens of thousands of dollars on their magical system.

They will send someone out there to knock on the door, take photos of the exterior, listen to see if there is a TV on, look to see if there are any lights on, see if there are any cars parked there.  

If pressed to lend a label to Minneapolis right now, I'd have to say "Decline" is the #1 that comes to mind for Minneapolis.

Big brands like Kaiser, UC Davis, West Elm, Press Juicery, and Yard House believe in the next 10 years here, not to mention large developers like the Grupe Real Estate, who are trying to buy up every piece of vacant land and multifamily they can find.

Whether it was post French revolution France putting price controls on grain, Poland price controlling TV's, Japan in the 80s setting prices on stock brokerage fees, post Dodd Frank limits on fees lenders charge. 

A little over a year ago,I bought a property that I SHOULD have pressed harder on.

So my sound proofing is focused in the second floor/ceiling of the first floor.For soundproofing, I do the following;1) I am mindful to seal up all of the second floor subfloor penetration.2) I installed 3" thick mineral wool (Roxul or Rockwool) insulation between the floor joist directly above the sheet rock.3) I use resilient channel to hang the ceiling drywall, which is 5/8" thick (per code for fire barrier, but is a bonus for sound).The above does a good job at reducing sounds like TV's, radio's, talking, etc.  

Open dedicated bank account/credit/debit card for that property.Establish relationship with handyman, plumber, etc..Get internet and TV set up 

You only need one "talking head" to come out on TV and say something to make a stock move significantly.
