Yes. The changes must be approved by HUD or a DE lender prior to beginning the work. If the change affects the health, safety or necessity of the dwelling, the contingency reserve can be used to pay for the change. However, if the health, safety or necessity of the dwelling is not affected and an increase in cost occurs, the borrower must apply monies into the contingency reserve fund to pay for the change. Should the change result in a reduced cost of rehabilitation, the difference will be placed in the contingency reserve fund; if unused, it will be applied as a mortgage prepayment after completion of construction.
