I do have a low interest vehicle loan that I did not pay off.

It is a retirement vehicle not people looking to get out of the rat race with cash flow. 

This will be a rather small facility not large enough for vehicles. 

I have just spent $8150 to repave my driveway, and I have set up concrete barriers and cones to discourage people from parking.To no avail, their customers still park on my driveway, blocking my tenants from moving their vehicle and blocking the driveway going into the back to the garage.

To me over leveraged means you have big car notes  your CC are close to or are maxed out and your only making minimum payments you go buy furniture and you finance it.. you buy real estate with the least amount possible down at market prices.And your cash reserves would only last you a few months to service all the debt.So no retail debt pay cash for anything you consume or use  OTHER Than a vehicle and decent amount of TRUE equity in your real estate no FO equity IE refi appraisal but you know the home would never ever sell for that on the open market. bascially follow Dave Ramsy and @Steve Vaughan  over the years on BP has written some really good comments on how to build an empire while balancing family life and fiscal safety..  

unfortunately with my current tax bracket, it's my understanding that i will be looking at about 30% (correct me if i'm wrong) in capital gains taxes and depreciation recaptureb) deferred sales trust, i like the idea of being able to invest in other investment vehicles but i'm not a very trusting person.

Most "investors" who are just looking and don't have an agent and then buy are not as familiar with the area or the investment vehicle as they should be.

1031 is a great vehicle, make sure you read all you can on it, know the rules backwards and forwards - no one cares more about your finances than you do - so gather as much info as you can so that way you can protect yourself.  

Reason is the seller is wanting to buy a vehicle before closing so they can be ready to move.

@Joey LlamasJust to clarify on what Roarke said, a 401(k) and Roth IRA are two different retirement vehicles.
