I worked as an independent contractor for over 10 years, finally decided to walk away from that security of having steady work, and income, so I could finally provide the level of service I wanted to, and homeowners deserved.I am a rare type, most others subs were more than happy with just doing enough to get paid, and move on.

I could see more landlords getting fed up and decide to redevelop their property into condos or townhomes if they can or sell to a developer .

Took about 6 moths bw deciding to do it and closing on my first.

Down there, making sure the roof is not blown off during a hurricane may decide whether a person will purchase your home or another down the street.

And then you have to do it again - one time - next month or however often you decide to print up flyers and hang/mail them.

How do you think they will feel if they realized that their electric bill is a higher because you decided to place solar panels?

This way your business and tax strategies are tailor-made to your needs/wants versus what the legislature decided.

The only thing that muddies things from your view is that HELOC only charges you for the interest calculated and you decide how much extra to pay. 

That lets me keep precise accounting of them and understand how that plays out for each property.  

The lender portion is your responsibility, if the lender just decides tomorrow they change their mind, it is not the sellers problem to deal with.I would agree with @Jason Hirko find something to keep them sticking with you if you are sure it is going to close.
