I'm feeling most drawn to a buy and hold rental investing strategy and like the idea of the BRRRR strategy in tandem with VA loans, basically refinancing VA loan backed mortgages to conventional loans once there is 20% equity in the home.

This vary heavily town to town. 20% down is great if buying strictly as investment but if you have a way of owner occupying I would explore that route and apply the 20% down to increasing value of property and instead using low money down loan. 

I am bullish on the FHA 203k and home-style renovation loans that allow you to leverage the cost of your renovation as part of your mortgage, which is just an insane deal, in my opinion.Do you have a specific area where you want to purchase?

Quote from @Jay Hinrichs:Jay, it does look like one of the strategies of this 711Rescue is to restructure the loan for their clients, but at 2x DSCR!

Non conventional just means the loan will not be sold to Fannie/Freddie so they do not have to follow those rules.

If you can find someone to loan you money for this endeavor please share their information with us all.

Right now, the best offers around me are for some 1.3-4 million, that only generated around 100k per year gross, so there would be a high chance of not cash flowing, and paying money, especially with a commercial loan (these buildings have more than 4 units).I was thinking that although the rental itself does not generate money, I would be able to deduct the mortgage interest, and depreciation from my personal w2 income and would be net positive.

That doesn't seem right about having to chase your money - but would need a lot more info to provide a better opinion. also are you investing in one property and is your name secured or you giving an unsecured loan? 

Or putting 20% down in a conventional loan so you can also avoid PMI.
