Many users mistakenly think this message is connected with loan limits. However, the FHA Maximum Loan Calculation is concerned with the costs of the loan. 

If you believe you are receiving this message in error, you should confirm you do not have a Seller Credit entered in the FHA Loan tab as a Seller Concession. Seller Credits should only be entered via Loan & Property > Purchase Credits. 

FHA Loan > Seller Concession

Loan & Property > Purchase Credits

If you have further questions about your findings or the FHA Maximum Loan Calculation, you should reach out to Fannie Mae, Freddie Mac, or HUD.
