@Arthur Means Historically, the financial point at which the PSLF makes sense, versus paying it off, is $60k in loans or more.

Taking 20k out might be prudent because the stock market is in the top quintile historically (valuation wise). 

But you also benefit (historically speaking, only) from a higher capital appreciation rate than other markets. 

I have a 3/1 in the historic district on Pounder ST for 60k.

@Dustin Salmon A Phase I (ESA) will tell you if there are any recognized environmental concerns, current or historical, and if really serious, a Phase II will be recommended.

(if you would like to learn more about how we find, and track off-market deals check out https://www.biggerpockets.com/forums/311/topics/556219-flip-in-the-historical-district-of-downtown-tucson ) Once under contract, our construction team put together a comprehensive estimate for the remodel and our investment team began running a financial analysis and a market CMA.

Have properties in that area historically appreciated at 1% over inflation?

Ten years after purchase the high appreciation markets will historically have better cash flow based on the initial cost when financed.  20 years after purchase this is more profound.However the value of the property has increased. 

I would think while rates are still historically low, you want to leverage while you can and save your cash.

Historically the S&P 500 has returned close to 10% (7% after inflation); not a bad return for a very passive investment.
