The IRS has spelled out guidelines for eligibility for the home buyer credit when co-borrowers purchase a property.
When a home-owning parent of an adult child co-signs for a mortgage and both names appear on the note, the IRS says that under some circumstances, the first-time home buyer can qualify for the whole amount.
The IRS says the parent doesn’t qualify for any portion of the credit, but if the child hasn’t owned a home during the three years preceding the current purchase and can qualify based on income, he or she can be allocated the entire $8,000 credit.
When unmarried individuals co-purchase a home and only one of them is eligible for the credit, then the full $8,000 can be allocated to the eligible buyer.
