I know this is a personal decision, but do you think it is a good financial decision to hold on to it until it is paid off so that we can use that money towards paying off our current house?

You bought land using cash or got the loanYou able to pre lease?

They both had other jobs when they bought because their first facilities didn't cash flow enough, but they stuck with it, paid off the debt and expanded and bought more! 

In 1974 I paid $16,500 for a 910 sq ft house in Richmond VA.  

Unless your internship will continue after your graduation and that internship is a paid internship. 

Next lease maybe have the lease end on the last day of the month and always spell out on the lease what damages are due to you if rent is not paid through the full term of the lease.

However, the loan statements will be in my name but paid by the LLC. 

I got my license pre 08 based on my HML experience in CA.but today its just like real estate at least in the states I know.. you need a mortgage broker / banker to sponsor you.. then work for a few years then you can apply to become your own banker broker.but do check the state laws. 

Do you have any records of how and when you paid contractor?

Their brokerage might not allow or have E & O Insurance for completing BPO's.Many appraisers also do BPO's but likely these days with so many regular home sales paying 400 to 500 a pop for appraisals likely do not do as many anymore.The cost offered to complete the BPO, timeline to complete (days,weeks), location (rural, suburban, urban core), Exterior or Interior BPO, whether map photos or drive by photos are required,etc.I do not think a broker/agent would want to complete a BPO for an unknown person as there is no surety of getting paid for the time invested.
