Biggest question ~ lets say we sell the primary home move into an investment and convert the investment to primary residence, what the some good ways to invest the income generated from the sale of the primary home (ideally in tax minimized conditions.).

I looked to minimize my risk in increase my potential.  

Upon re-reading my post, I realize I've not clearly conveyed the intent here, which is to minimize the amount I borrow from the local bank. 

A VA Appraisal is just that an appraisal with minimal cursory look at some items such as is the water on, turn the heat on and a ground level visual of the roof.

It is minimal enough that it could easily be resolved with a few hours of work which we are prepared to do.

Most lenders will not allow you to get a loan for the down payment because they prefer your debt to be minimal before their debt hits your credit.

The price was right, with very minimal work.

Having someone there for you helps in big ways, even if it is just emotional support.My second tip is to buy something with minimal work, especially if you don't have a team set in place.

Numbers based on a sold property and optimistic scenario (e.g. low vacancy, minimal repairs etc).

Downsides are there's more turnover to deal with and can be more management with issues between roommates... this can be minimized with good tenant screening, leases, roommate agreements.I make sure the house is profitable as a normal rental along with room rental incase something comes up and strategy needs to change.
