If you’re confident the remaining funds can be reinvested into a stronger opportunity, like your new duplex project, it might be worth it.

However, you could look into a “construction exchange” where the funds are used to improve a new property acquired through the exchange, but it must meet specific IRS rules within the time frame. 

Selling multiple properties in a 1031 exchange to consolidate funds for one investment property is allowed, but the property must initially be used solely for investment.This post does not create a CPA-Client relationship.

You can reach out to the Title company and see if there are any funds remaining for dispersement, if so then ask if there is a way to make a claim to those funds.

Quote from @Michael Daniel: @Jaycee Greene these are low income areas however there's a lil room for rent increase but not much. 

Each time I wire funds down to Belize the recipient has to go to the bank and sign why they are getting the funds.  

Meaning that if you fund a $5K EMD and then decide not to close you lose the EMD, or you pay for an inspection up front and risk missing out on the deal while you're waiting for the report.
