Selling SFHs to buy an apartment building

[Steve S.]

I have 6 SFH which are all rentals in Florida. I am moving to Texas in two years and would like to purchase a small apartment building 20-30 Units. What is the best way to sell all properties and pay the least amount of tax? If its even possible to 1031 into commercial, from a SFH rental, I wouldn't be able to sell all and find an apartment within allotted time (90 days I believe). Also is it possible to cash out refinance all homes and wrap them all into one mortgage?? Anyone know a lender in Florida that I could talk to about that?
