The 203(K) loan is usually done as a combination loan to purchase a fixer-upper property "as is" and rehabilitate it, or to refinance a temporary loan to buy the property and do the rehabilitation. It can also be done as a rehabilitation-only loan.

Plans and specifications for the proposed work must be submitted for architectural review and cost estimation. Mortgage proceeds are advanced periodically during the rehabilitation period to finance the construction costs.

For a list of participating lenders, call HUD at (202) 708-2720.

If you are a veteran, loans from the U.S. Department of Veterans Affairs also can be used to buy a home, build a home, improve a home or to refinance an existing loan. VA loans frequently offer lower interest rates than ordinarily available with other kinds of loans. To qualify for a loan, the first step is to apply for a Certificate of Eligibility.

Another program is the Fedeal Housing Administration's Title 1 FHA loan program.

However, the 1997 tax changes virtually eliminates the capital gains tax for most homeowners (the exemption is $250,000 for single homeowners and $500,000 for married homeowners.).

All buildings must be issued a building permit and a certificate of occupancy before it can be used. During construction, housing inspectors must make checks at key points. Codes are usually enforced by denying permits, occupancy certificates and by imposing fines.

Building codes also cover most remodeling projects. If you are buying a house that has been significantly remodeled, ask for proof of the permits involved before you purchase to avoid future liability for fines.

The tax code does not allow deductions for the demolition or significant alternation of a historic structure.
