Pitfalls in the Financing of Home Construction

Pitfalls in the Financing of Home Construction
 

March 22, 1999

" My wife and I are considering having a house built for us and I would like to know the basics of combination construction/permanent mortgages. What do we look out for?"

Construction can be financed in two ways. One way is to use two loans, a construction loan for the period of construction, followed by a permanent loan from another lender, which pays off the construction loan. Two loans mean that you shop twice and incur two sets of closing costs.

The second way is to use a single combination loan, where the construction loan becomes permanent at the end of the construction period. One loan means that you shop only once but you must shop construction loans and permanent loans at the same time. The single loan approach results in only one set of closing costs.

Some lenders (primarily commercial banks) will only make construction loans. Others will only make combination loans. And some will do it either way.

Construction loans usually run for 6 months to a year and carry an adjustable interest rate that resets monthly or quarterly. In addition to points and closing costs, lenders charge a construction fee to cover their costs in administering the loan. (Construction lenders pay out the loan in stages and must monitor the progress of construction). In shopping construction loans, one must take account of all of these dimensions of the "price".

Lenders offering combination loans typically will credit some of the fees paid for the construction loan toward the permanent loan. The lender might charge 4 points for the construction loan, for example, but apply 3 of the points toward the permanent loan. If the borrower takes the permanent loan from another lender, however, the construction lender retains the 3 points. This credit plus the one set of closing costs are major talking points of loan officers pushing combination loans.

The rebate offered on combination loans makes it difficult to compare these loans with the two-loan alternative. For example, lender A offers a construction loan at 4 points with 3 points applicable to a permanent loan, while B offers an untied construction loan at 2 points. Going with A means saving one point on the construction loan but this is no bargain if A's terms on permanent loans are not competitive.

For example, suppose A offers a permanent loan at 6% and 3 points, while lender C offers the same 6% loan at 1 point. Then if you selected A, you would pay a total of 4 points on both loans, but if you had selected B for the construction loan and C for the permanent loan you would have paid only 3 points in total. A is above the best price available in the permanent loan market by more than it is below the best price available in the construction loan market.

Further, once you accept a combination loan deal that involves a significant rebate from the construction loan, shopping other lenders for a permanent mortgage after construction ends is likely to prove fruitless. So long as the combination lender is not above the market for permanent loans by more than the rebate plus closing costs, you cannot do better by finishing the deal with another lender. You're hooked!

This means that you cannot properly assess a lender's combination loan without comparing that lender's terms on permanent loans with those of other permanent lenders. This is why you must shop construction loans and permanent loans at the same time. If the combination lender is above the market on permanent loans by an amount that is less than the saving on the construction loan plus closing costs, you go with the combination loan. Otherwise, you go with two loans.

An alternative is to ask the builder to finance the construction for you.  Then you have only the permanent loan to worry about.  This option is discussed in Should the Builder Finance Construction? 

Note: Interest on construction loans is deductible as soon as construction begins, for a period up to 24 months, provided that at the end of the period you occupy the house as your residence.
