Here is my situation: My husband and I have a house that is over 60 years and we still owe a mortgage on it. The house is in need of lots of repairs and we feel that it would be a money pit if we tried to just make all the repairs, so we are wanting to tear this old house down and build a new house on the same land the old house sits on. I want to know if there are any banks or mortgage companies that will give us a loan to pay off the old mortgage and also finance a new one.

    How much do you owe on the house now? What is the market value as-is? How much would it cost you to build a new house, and what would it be worth (roughly)?

  • I think the main question would be the value of the land in relation to (a) your current mortgage balance outstanding; and (b) the estimated cost of building a new home. Jan 15, 2018 at 14:27

You're effectively looking for a mortgage for a new self-build house. At the beginning, you should be able to get a mortgage based on the value of the land only. They may be willing to lend more as the build progresses.

Try to find a company that specializes in this sort of mortgage.


I could be wrong, but I doubt you're going to be able to roll the current mortgage into a new one. The problem is that the bank is going to require that the new loan is fully collateralized by the new house. So the only way that you can ensure that is if you can construct the house cheaply enough that the difference between the construction cost and the end market value is enough to cover the current loan AND keep the loan-to-value (LTV) low enough that the bank is secured.

So say you currently owe $40k on your mortgage, and you want to build a house that will be worth $200k. In order to avoid PMI, you're going to have to have an LTV of 80% or less, which means that you can spend no more than $160k to build the house. If you want to roll the existing loan in, now you have to build for less than $120k, and there's no way that you can build a $200k house for $120k unless you live in an area with very high land value and hire the builders directly (and even then it may not be possible). Otherwise you're going to have to make up the difference in cash.

When you tear down a house, you are essentially throwing away the value of the house - when you have a mortgage on the house, you throw away that value plus you still owe the money, which is a difficult hole to climb out of.

A better solution might be to try and sell the house as-is, perhaps to someone else who can tear down the house and rebuild with cash. If that is not a viable option (or you don't want to move) then you might consider a home equity loan to renovate parts of the house, provided that they increase the market value enough to justify the cost (e.g. modernize the kitchen, add on a room, remodel bathrooms, etc.

So it all depends on what the house is worth today as-is, how much it will cost you to rebuild, and what the value of the new house will be.


Unless one or both of you are professional house builders with years of experience building houses, this is a horrible idea. You're almost certainly going to go massively over budget. Even if you hire someone who is a professional builder, you're going to have lots of serious problems. I've never heard of a non-professional having a good time with such a project.

Sell the house, buy one you prefer or repair the current one. Demolishing the existing structure and building a new one from scratch will cost a lot more.

You are being too strict with yourselves. In many jurisdictions you can tear a house down leaving only the foundations and still call it a renovation. That means as long as you can get a mortgage on the existing house, and as long as you can show that in the end the house will be worth more than the amount you borrowed then you should be OK.
