Restriction on Additional Debt

For the term of the restrictions beginning from the purchase of a dwelling unit, or from the date of occupancy of a dwelling unit built on a vacant lot purchased as a vacant lot, whether ownership of the dwelling unit or vacant lot is from an original or subsequent purchase, and whether by lease, assignment of lease, deed, or agreement of sale, if the owner wishes to make additional mortgage loans on the property during the term of the restrictions, such additional mortgage loans shall not be made without the prior written authorization of the Housing Agency. The only additional mortgage loans that may be approved during the restriction period are loans whose proceeds will be used for capital improvements to the dwelling unit, to build a dwelling unit, or to pay for catastrophic medical expenses incurred by a member of the owner's household. Additional mortgage loans shall only be authorized by the Housing Agency when the total of all mortgage debt to market value is a ratio that does not exceed 80%.
