It is impermissible for you
to take an interest-bearing loan. This is because Allah prohibited Riba (usury/interest) and gave a strongly-worded threat to those who deal in usurious transactions. Moreover, the Prophet (peace be upon him) cursed the person who consumes Riba, the one who gives it, the two who witness it and the one who writes it down. Thus, Riba is not permitted under any circumstances whatsoever. You may not buy the place to which you referred unless you have the financial ability to buy it without resorting to Riba. Moreover, you can offer Salah as best you can, in one congregation or separated into a number of congregations at different places.
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
