Extending lease might be best bet.    

It creates over-leverage and the performance of one property is dependent on the other.

If there's a hole, it may be a red flag.b) sensitivity analysis: I examine all the assumptions, and make sure I can live with the worst case scenarios.c) "Stall and see": if they are getting money over multiple years, and there is no penalty for investing later, I would usually wait so I get some real performance data, versus having to look at theoretical pro forma information.d) Recession stress test: I will not invest in anything, until I subject it to recession level stress and see if I can live with the result.

So Real estate is the best bet? 

So you’d be ok coming out of pocket another $130k and paying $780k for this property if the builders fail to perform?

The new property has to perform enough better than what you have to pay the higher interest rate on the higher balance, AND ADDITIONAL profit just to payback the $65k you lost selling.

Owners mistakenly ASSUME all PMCs offer the exact SAME SERVICES and PERFORM those services EXACTLY THE SAME WAY, so price is the only differentiator – so, they often select the first PMC they call or that calls them back!

While BP has a rent estimator as does rentometer.com (both allow a few free uses, I believe), I agree with @Zachary Deal that your best bet is to seek out guidance from either the listing agent or a property manager well-versed with the area.
