Potential BRRRR deal requires proof of funds letter

[Douglas A Lewis]

I have a property that I’m putting in an offer on but the seller is requiring a proof of funds letter. I thought I could line up financing in the due diligence phase of the deal. The property needs a lot of work so I cannot use a traditional bank yet for the financing. Should or could I get a letter from a hard money lender? Or what other idea would you suggest?
