Frequently Asked Questions

Can a master plumber with significant write-offs qualify for a mortgage?

Yes. A bank statement loan qualifies income from actual bank deposits rather than Schedule C net income. A master plumber who grosses $130K+ but shows much lower net income due to legitimate deductions regularly qualifies through Non-QM bank statement programs.

Does having a master plumber’s license help with mortgage qualification?

Indirectly yes — a master license indicates specialized, in-demand skills and typically corresponds to higher, more stable income. It signals to Non-QM underwriters that the borrower’s income is durable and backed by licensure requirements. It does not change the income calculation itself.

Should a high-earning master plumber use 12 or 24 months of bank statements?

If income has grown significantly in the past 12 months compared to the prior year, the 12-month program may produce stronger qualifying income. For stable or gradually growing income, 24 months typically works well. A Non-QM loan officer should model both scenarios.
