Most of your question depends on the price range your willing to invest. 

I found a couple in my price range, but I don't know if I should get a loan or maybe borrow money from my parents.

Then you will be making monthly payments on the interest amount (currently I have seen that in the 11-12% range).

Definitely recommend getting guidance from a real estate CPA and a cost segregation expert, to see if what you can save is worth the cost and effort of doing this for this property price range.

I do believe that the ARV could possible range between $200k-210k.

It's not going to be a fast ticket to wealth but if you could 1031 into a property in the 1-2M range(guessing) you'd get on a faster track.

I am looking at a brand new house in the 140-150k range that will bring in about 1200-1300 per month in rent.I have about 60k to invest.

If you do move it to an LLC it would be for asset protection purposes, however to other's comments - the 1 LLC won't be sufficient. 

But cash out is different  Hey David, Yes, it was a short-term rental (STR).0.74 acreageThe property was marked as rural on the appraisal.1007 form not utilized 75% of AirDNA data was used for determining market rents.The potential loan-to-value ratio (LTV) for the cash-out refinance could range between 70-80%.Let me know if you like to take a look at the property.

What we should want is for the rate of price appreciation (inflation) to level off in the 2-4% / yr range.
