@Kezia Edmonson, it's all about the valuations as @Jon Taylor mentioned.In your 1031 exchange you must purchase at least as much investment property as you sold in order to defer all tax. 

This allows us to 1031 exchange post-sale into a new deal, compounding cash-on-cash returns and deferring capital gains.Let me know if you’d like to discuss further!

I would like to 1031 exchange these properties into investment properties in South Carolina.

Quote from @John Reagan Johnson: I am new to the real estate industry and am looking to connect and exchange businessIf you are new I would suggest something totally different. 

However, I am seeing more interest in MTR's and have a colleague that does well buying condos and renting out to traveling medical workers and foreign exchange students.  

If you're going to reinvest the proceeds you might want to consider a 1031 exchange or a cash out refi to generate the investment funds you desire for your next project.

@Damon AlbersSince those properties are used for investment they would qualify for a 1031 exchange.

@Jeff Shaver There is no specific statutory time frame before you can do a cash out refi after completing a 1031 exchange.

You will want to consult with a lawyer.In regards to your last two questions here's some background on what makes a contract valid and enforceable:Offer: A promise to do or not do something within a certain time period Acceptance: A clear and direct statement that all terms and responsibilities are accepted Consideration: A legal and adequate inducement given in exchange for the promise Capacity: The parties to the contract must have the legal capacity and competency to contract Awareness: A party must be aware of the contract Legality: The contract must be legal in the jurisdiction it will be operating in***Not legal advice*** Steps I would take: -Review contract in detail to understand each counterparties responsibilities (if you are not aware)- Email a copy of the lease to each of the tenants listed on the lease and reiterate lease expectations for termination notice, rent payment etc. - If the lease was signed via Docusign (other esign may have same ability) - you can go to the envelope, go to history and view the IP addresses for each action taken.

I have to agree that a 1031 exchange may not be the best strategy.
