We spoke with both the developer's representatives, and with our lawyer regarding a lump sum payment. From what we learned, a purchaser has the unilateral right to pay the balance owing on occupancy, and avoid the 'Phantom Rent', if that election is made during recision period associated with the original purchase. Subsequent to that time, any request for a lump sum payment on occupancy, above what was in the original (or subsequently amended) purchase agreement, is at the grace of the developer, and from what I understand, not often granted. In our case, the developer would not agree to accept any lump sum above the 15% payment on occupancy which was already established in the purchase agreement payment schedule.
Regarding the 'Phantom Rent' - the purchase agreement stipulates that it is calculated on the balance remaining at time of occupancy (in our case 70%) times a prescribed rate. It turns out the prescribed rate is the rate that is posted for either a one year or a two year (I forget which) closed mortgage by the Bank of Canada, with the prescribed rate for February being 3.25%. The rate is updated on a monthly basis. In our case, and I would presume applicable elsewhere, the developer wants a series of post-dated cheques for the Phantom Rent, maintenance and taxes at the time of the initial occupancy. How then to handle changes which take place in the prescribed rate in the months between initial occupancy and final close? It turns out that any changes in the rate become month to month variances, which are itemized and settled as part of the adjustment schedule for the final close.
That is the limit of my understanding - based on several telephone calls with both our lawyer, and representatives from the developer. I hope it helps.
