Under a completion guaranty, sometimes referred to as a
“cost overrun guaranty,” the guarantor typically
guarantees any excess of the cost of completing construction over
the portion of the construction loan allocated to funding
construction costs.
The lender will usually have all or some of the following three
remedies: (i) requiring the guarantor to complete
construction, in which case the guarantor will be entitled to draw
undisbursed amounts of the construction loan allocated to
construction costs, as these costs are incurred; (ii) the
lender itself completing the construction, with the guarantor being
obligated to reimburse the lender for costs incurred to the extent
they exceed the undisbursed loan amount allocated to construction;
and (iii) most importantly, collecting from the guarantor a
payment in an amount equal to the estimated cost of completion less
any undisbursed loan proceeds allocated to construction, which is
referred to as a “liquidated damages”
