If you haven't caught up, here's the tl;dr - I acquired a bunch of properties last year with a turn key company called Own It Detroit.

Since currently I have "excess income" from my w2 because I do not need to pay primary mortgage, I could re-invest the money to property that gives "lifestyle benefit", just like you building cabin in AZ/lakeside/etc with minimal risk.

It's not as cut and dried as some people think. ;-)As @Chris Seveney: says, "keep the house and restructure the debt" I've done that for people too.

I think almost half the cost comes from the teen driver.Additional $345 annual to add $1M excess uninsured / underinsured motorist coverage.A $2M umbrella on top of a $2M STR policy might seem like overkill, but it's a big three-story house with seven bedrooms, max 19 guests. 

I would focus on screening your tenants for background, credit, and income to try to avoid an eviction and excessive damage to your property to minimize your turnover expenses and vacancy loss.  

Easement by necessity is state to state each has their own rules and its not cut and dry as I have found out over the years.. but I will let Peter answer  he is the expert.

You will exponentially increase your dry powder.

In a recent post about how to minimize the taxes on rental income it was mentioned that: Setting aside reserves is an expense, so long as they are not excessive.

Also they need to dry that area if it keeps growing mold. 

Some investors choose or get forced based on code to upgrade the excessing panel to 200amps.
