Deducting Rental Property Mortgage interest from a Multi Property Blanket Loan

[HeartlandDevelopment]

Hello, 

I have one blanket loan on 4 single family rental homes.  I have received one 1098 with the yearly mortgage interest paid. 

The rental property mortgage interest is deductible as an expense and the most logical path seems to be to divide the interest in 4 and allocate 25% equally to each home.  However, I worry that the IRS audit algorithm will flag for audit because I will have interest amounts that do not match a 1098.

Should I instead allocate all interest to one of the properties for less risk of audit?

If you report the rentals separately by units, then the mortgage interest should be divided among the units, as long as the total interest claimed does not exceed the interest reported on form 1098.
