Federal Laws Prohibit Discrimination of 7 Protected Classes, Massachusetts has added 8 more:-02.Always know more of the Rules/Laws/Regulations than ANY Tenant.

I’m wondering how I can protect myself if they somehow rack up the bills/ abuse the policy. 

So your saying select No Damage Protection and just submit an extra charge when it's warranted? 

I’m a fan of harvesting the equity to buy more and more cash flowing properties with zero out of pocket cash for down payments.

At harvest time.  60 trees per acre.  

It's hard to harvest equity on these plays, unless you commit, long-term, towards very light leverage, as the only practical ways to benefit from the equity in your portfolio, if you plan to never sell it, only exchange it, for a lifetime, are to spend the cash flow, or cash out refi.

But, if the $100k is coming in from a $3,000 acre from which has already been harvested $20,000 in TDR credits, that's not a bad ROI. 

The overall value of the land and potential subdivision and the harvested lumber will be 10 times the original cost.  

And I like to harvest equity to buy more cash flowing properties.

With some of my clients, I've seen discounts of 30% to 90%.Here is a real-life example: I invested in a $50K note; it was second TD but with significant equity (over $200K) protecting my investment.
