Thanks, Janet. Good morning, everyone. I will review our investment activities for the fourth quarter of 2015 and for the full year. On the disposition and asset recycling front, during the fourth quarter, FSP sold Montague Business Center in north San Jose, California for $30,250,000 and recognized a gain of approximately $12.9 million. Montague Business Center consisted of approximately 146,000 square feet in 2 single-story buildings that were originally acquired back in 2002.
For 2015 in total, FSP recycled out of 4 properties for $87,250,000. Those included Eden Bluff in Minnesota, Willow Bend in Dallas, Park Seneca in Charlotte and Montague Business Center in north San Jose, and those resulted in gains of approximately $23.7 million in total. Additionally, and as we mentioned during our last conference call that some transactions could spill over into 2016, this did, indeed, occur. Specifically in January, FSP received the full repayment of our approximately $37.5 million first mortgage loan via property sale of 385 Interlocken.
Including the Interlocken loan repayment, we completed roughly $125 million in total recycling over approximately the past 12 months. FSP remains committed to recycling out of our noncore assets within the portfolio when appropriate pricing is achieved. Accordingly, FSP expects to transact continued dispositions during 2016, and they are likely to be in excess of 2015. We are not providing specific disposition guidance as there are a number of moving pieces that make such guidance potentially less meaningful.
Moving pieces include: number one, that we're not sellers at any price; two, that some properties are being prepared now by their respective selected brokers for actual price discovery, and we do not yet know if they will meet, exceed or miss pricing expectations; three, one asset is actually currently under agreement now and is in its due diligence period. But until we know the outcome of that process, we don't want to assume anything; and four, there are several properties that we believe would represent strong potential disposition candidates that -- but that we believe still have possible rent roll value-creating enhancement opportunities that we would like to try to make happen prior to their marketing, and this will gauge the potential timing of their respective sales. We'll update our disposition efforts quarterly.
On the acquisitions front, FSP continues to seek new investments and is underwriting both on- and off-market opportunities, primarily in our core markets. We continue to focus on self-funding these new investments by working to utilize disposition and loan repayment proceeds. And we're looking at a number of opportunities and are seeking to be a net acquirer in 2016. We do recognize that this objective will be opportunity-driven though and be connected to our recycling and disposition efforts.
On the development front, we continue to work in earnest with our intended partners on our potential downtown development in Minneapolis at 801 Marquette. Our work is now focused on finalizing the actual costing and feasibility with our development partners. This consists of addressing the specific needs or programs of each piece of the development, office, hotel and apartments. We do anticipate that this work will be largely completed in approximately the next month. And from the work we have seen so far on the office portion, which is still subject to change, the office piece of the tower is coming on in line with our preliminary estimated cost of between approximately $80 million to $90 million, including the land. In the meantime and as Janet mentioned, we're fully engaged on pre-leasing efforts in the new potential tower development.
Now at this time, I'd like to turn the call back over to George Carter to close. George?
