hi, I am restarting my RE investments, and looking for opinions here on my primary residence. 

Electrical submetering involves the installation power meters (also called power monitors, electrical meters, or energy monitors) that can measure energy usage after it reaches the primary utility meter.

The primary goal is to recover all (or most) of your cash invested.  

Currently my portfolio consists of the duplex, the single family home w/ guest house we are closing on Friday, and our primary residence which is a SF 3/2.

6, why is that you cannot get a traditional mortgage loan for a flip?

I want to hear your answer based on your primary research.

You could take a personal loan to cover it, or a line of credit on your primary home, if you have equity

Just want to make sure I am able to do this.I have owned my primary residence since 2008, before I was married.

Scenario A (typical) - $500k duplex-$125k down-$375k mortgage at 4.6%Scenario B (modular financing) - $500k duplex-$125k down-$260k mortgage at 4.6%-$75k HELOC on primary residence-$40k loan against 401(k) (technically this would be $165k down, but you get the point)In scenario A, paying off the mortgage quickly makes zero improvement on cashflow until you pay it off completely, or refinance, and there's no point in that if your rate is locked in lower than current(or future) market rates.Scenario B could involve higher interest rates on the HELOC and the 401k loan, but you have multiple, simple, easy options for increasing your cashflow, and then you don't end up playing as much in the overpriced, volatile stock market.
