Ironically, I actually did a cash out refi just about a year ago to date to bolster the fund pool for the next move and to reduce my rate. 

Look at it this way, if you are paying $10,000 a year in interest expense, you can get back maybe $250 worth of that in reduced taxes.

and lastly, When moving out a tenant does Incentivizing referrals really produce viable tenant/reduce turnover …… please help, Our single family is almost done and I’m worried about being the best i can be for the business.

MFR rate and term refi LTV is 75% which on your 305K value is a new loan of only 229K +/-, which means you are coming to closing with 13K to reduce the loan balance.

I was not 100% sure what documents to use for the double closing.I don't know everyone's opinion, but mine is this: double closing adds two closing costs to the transaction instead of one reducing the spread in the deal.

Buying a multiplex with reduced rents will affect new buyer's cash flow/profit and is sure to be reflected in the price the RE sells for.I gave out 6 maximum allowed rent increases this year having never given that size rent increase previously.

Less stress in my opinion. 

I stopped stressing a long time ago about interest rates (within reason).

Other hand having high interest rate debt would stress me out especially if things go sideways.

Lower Maintenance - downsizing typically reduces the amount of labor required to maintain the home because there is less area available to clean.
