Historically I can't think of a single scenario where this hasn't gotten away from a government (drastically) and became a catalyst for hyperinflation.

You should be asking for profit and loss statements in your due diligence which will (better) include historical utility costs. 

You can normally raise the rent about 3% every year.Another big consideration in your decision is the historical history of the rentals in that area or its future potential versus the selling demand in that area so your net income could go up. 

I live on an historic road with brick pavement. 

In seattle 1940s 900 square foot houses aren't worth the 800k people spend- it's the location/ land value on historic queen anne hill. 

Given returns are fairly muted now and historically the stock market has returned approximately 7% annually, does it make sense moving from a regular 401k to a my solo 401k and investing that money in real estate even though there are no tax benefits to be had.

The price is good but I been waiting for confirmation that I should pull the trigger.could be the fear of my first purchase.idkKeep in mind the biggest item to pay on a rental is the mortgage we are in historic low rates ?

Cap Rates have historically been above 10+.

To get the 10% NOI you need to pick markets that historically don't appreciate.
