One of the biggest mistakes newer investors make is over-rehabbing houses and spending too much money on these low ARV homes.

Sure, one can neglect these.

There is no point in doing a 1031 exchange if you expect a loss from the transaction.A 1031 is meant to defer your gain.There are numbers which you can analyze and stress which is not easy to analyze.It looks like you are stressed with this investment and I would sell.I personally, however, would look to make the improvement for $10,000 to get one of the other units up and running.

Should I add one or two more? 

Once the baby comes and one more on the way, even better.  

One thing I suggest doing as you do your research as well is to find a property on AirBnB that you like. 

Do it yourself with TurboTax (or similar software)If your rental is pretty simple (one property, basic income & expenses), you can learn the basics and still save money.

I own one rental house in Cypress, but with the current market I have not been able to find another existing single family home to buy that looks like a good investment. 

When it seems like they have a final bid and no one is willing to increase it, they will often times go talk to the owner for a few minutes.
