Take her out for a lovely dinner and treat for a girls night out at something she loves to do in appreciation. 

I'm not looking into house hack, although that would be viable if I was younger.I just have capital saved and with the vast array of investment options in real estate I been pondering what the most effective way to do it would be.I'm still considering a multi family but instead of just going into it with the narrow point of view of using it as a long term rental I should be be considering any unit for possible STR/MTR depending on the market as well.With the whole Airbnb arbitrage I thought it would be a good way to enhance cash flow.

We're able to afford the place as a 2 flat, but still pondering legal options for monetizing the garden unit, if any exist. 

You cannot legally have "all guy" or "all girl" houses.

You have risk of loss (yes, boys and girls, stocks do go down) and you probably aren't going to generate enough capital gains or dividends to cover your rent.Recalculate and get back to us please.

Thoughts to ponder. 

For the most part, the guys and girls at the ground level are still great and focused on what they do!
