The federal tax plan that is on the table is proposing a number of changes that would affect home buyers, home sellers, and homebuilders, according to the Chicago Tribune.

The House version of the bill would cap mortgage interest deductions on loans of $500,000, and the Senate version would keep the cap at $1 million, according to the report. The bills could also affect state and local property tax deductions.

The uncertainty surrounding the tax bill will likely have an effect on big financial decisions, like home buying and selling. 

“People are cautious and aren’t going to make large purchases until they see what’s going on with this tax bill and how it’s going to affect them,” said Michael Menn, president of the Home Builders Association of Greater Chicago, according to the report.

Additionally, real estate industry leaders and homebuilders have expressed concerns that cutting property tax deductions could erode home values and decrease sales. Representatives from both the real estate and homebuilding industry are expected to lobby for preservation of mortgage and property tax deductions, according to the report.
