HUGE variances with lenders, HELP!!

[Emmy K.]

Quick question, my husband and I have stumbled upon a 12 unit deal in a great area needing some TLC. Price we have agreed to is $675,000. It appraised last year for $830,000. Has some differed maintenance but we have set more than enough aside, we think. 

My question is lender A requires 25% down,($168,750) 5/20 ARM with rates starting @ 5.25.

Lender B says we can do 10% down, ($67,500) 5/20 ARM with rates starting @ 4.25.

Should we be suspicious of Lender B?(Republic Bank in KY.)

Lender A (SYB in KY) says we should be suspicious...

ANYinsight or advice is greatly appreciated, meeting with Lawyers and lenders Monday morning. 

TIA!!!
