Divorce buyout with a second mortgage: how much cash can you actually get?

I recently worked through a divorce buyout where the goal was pretty simple:

One spouse wanted to keep the house and needed about $140,000 to buy out the other spouse.

The harder part was figuring out how to get there without giving up the existing first mortgage.

That is where a second mortgage can make a lot of sense. But there is one big mistake people make when looking at these scenarios:

The loan amount is not the same thing as the cash you actually receive.

Here is how I look at it.

Start with the actual goal

Before we talk about loan amounts, rates or payments, I want to know:

How much money do we actually need?

In this case, the buyout was approximately $140,000. There were also other debts that needed to be paid and some property taxes due.

So the real question was not, “Can we get a $190,000 second mortgage?”

It was, “After everything gets paid, will there still be $140,000 available for the buyout?”

That is a very different question.

First, make sure there is enough equity

The home was discussed at approximately $815,000. The existing first mortgage was about $479,585.

If we added a $226,000 second mortgage:

Combined loan-to-value, or CLTV, compares the loans against the home's value. That matters because second-mortgage programs have limits on the total financing.

For example, if a particular program allowed financing up to 90% of the home's value:

That does not mean someone automatically qualifies for that amount. Income, credit, appraisal, program rules and other factors still matter.

But it gives us the outside boundary to test. For a line of credit, we also need to confirm how the lender counts the available line as well as the drawn balance.

Then look at the cash that is actually left

We also looked at a $190,000 second mortgage.

At first glance, that sounds like more than enough to cover a $140,000 buyout. But look at what happens once everything else is accounted for.

So even with a $190,000 loan, there was only about $98,000 left in that calculation for the divorce settlement.

If the buyout requires $140,000 entirely from those proceeds, the plan is $41,683 short, or about $41,700.

That is the number I care about. It tells us this version needs another funding source or a different plan. It does not mean a loan closed with that shortfall.

Keeping the existing first mortgage can still be valuable

If the existing first mortgage has a good rate, replacing it with a new mortgage may not make sense.

A second mortgage lets us potentially leave that loan alone. I would compare two options:

• Keep the first mortgage and add a second.
• Refinance the property into one new mortgage.

Then compare the monthly payment, closing costs, cash available for the buyout, total interest cost and what happens to the existing first-mortgage rate.

There is not one answer that works for everybody. The math helps us decide.

Title and mortgage liability are different

Divorce adds another layer.

Changing ownership does not automatically remove someone from the mortgage. The attorney and title company may handle the ownership transfer while the mortgage still has both borrowers obligated on the loan.

If an assumption is available, such as on certain FHA loans, that may be worth exploring with the servicer. The ownership, liability and financing steps need to fit together.

Why borrowing a little more can get expensive

Sometimes a higher loan amount moves the total financing into another pricing tier.

For example, imagine one option puts CLTV at 84.9% and another at 86%. Crossing a product's threshold could change the pricing. Those percentages illustrate the question, not a universal program rule.

The higher rate may apply to the entire second mortgage, not just the extra money borrowed.

So I do not only ask, “How much more can we borrow?”

I ask, “How much more cash do we actually receive, and what does that extra cash cost us?”

Those are very different questions.

The simple way to look at a divorce buyout

If you are trying to keep the house during a divorce, I would work through the numbers in this order:

1. How much does the other spouse need to receive?
2. What other debts or expenses have to be paid?
3. What is the home realistically worth?
4. What is owed on the existing mortgage?
5. How much second-mortgage financing is available?
6. What will actually be left after costs and payoffs?
7. What will the new monthly payment be?
8. Does keeping the existing first mortgage still make sense?

That gives us the real answer. Not just how much you can borrow.

How much money actually gets where it needs to go.

That is usually the most important number in the conversation.

This example is based on a real mortgage discussion with identifying information removed. Any numbers are illustrative and are not current loan terms or a commitment to lend. Loan programs, rates, property values and borrower qualification vary.
