They also have a parking spot that is included with no extra charge. Rent

Since AL and the other review sites are a marketing expense, you should expect that most of the companies advertising there charge rates that take that expense into account. 

They have been convinced  by incompetent landlords that turn over is very expensive, so expensive that they live with bad tenants and charge rent below market hoping not to face a turn over.

Only do 1 yr leases... actually, I prefer M2M, but I understand we're in a different market.I say, do a small upgrade (ie: new light fixture, or change electrical outlets to have the chargers included), and then raise the rate something  reasonable, $50 this year, and do the same next year, and the year after that. 

That's tough, yes I would definitely look to charge rent for a business.

You didn't specify so I will assume you're not planning to charge rent while your children use the property. 

Should I replace the charger and move on??

As you're well aware, it is possible to live frugal and still be considered a success :)@Jeff Brower I was once that friend holding up the keys to shiny new cars, beginning with a Jeep, then a Subaru WRX, Dodge Charger, & Jeep SRT8 Grand Cherokee...from a $3k loan all the way up to $24k for cars that I no longer own.

Depending on your personal goals, there may not be enough of a spread between what you will pay out monthly in mortgage, taxes, and utilities and what you can charge. Real

I am considering putting my 1969 Charger up for trade on the right multi property in my area, I paid 25k for this car a few months ago and now the value has doubled, it's a General Lee, what, if any, taxes would I have to pay if I did a straight trade on a property?
