Does the National Guard make your house paynents if call to active duty?

Not likely. You would still be responsible for house payments. However, you would be paid some amount by the National Guard, probably more for active duty.

No. While on active duty you receive regular duty pay and benefits, not from the National Guard (or Reserves), but from the Federal Government (Army, Navy, Air Force) (Marines & Coast Guard fall under Navy). Also time served on active duty counts toward retirement.
