1031 Closing Costs on buyer side

[Liz Scott]

Hello. I'm getting hung up on "allowable exchange expenses" vs the requirement to reinvest all equity. I understand that exchange expenses can add to or subtract from the basis as a whole, but in a situation with debt involved, would those expenses impact the debt before the equity? In my case, there are a few different items I can get credit for at the closing table: 1) lender credits (negative points); 2) seller-paid repair costs; and 3) because the appraisal came in low, seller suggested if I pay broker commission, they would give credits to meet the appraised value. Can I take that cash home at close? Can I set it up with escrow for specific vendors? 

The replacement value is 724k with 275k in equity; new property is 805k with 245k down payment. Can I use (275k-245k) 30k towards closing costs and still get money back from credit overages?

Thank you in advance...
