"You inform me that a year ago you bought a home in another neighborhood and are constantly having problems. (Seemingly it was an investment and the owner was having problems associated with the property).
Many times this happens because one is not as careful as he should be in fulfilling the mitzvah of tithing from the profits of the real estate investment, the home. Even if in your case you have not tithed until now, you should tithe now. Additionally, you should give to tzedaka the amount of money you were supposed to tithe but did not."
