During their-presidential election-campaign,
Obama & Biden spoke of either:
a "$500" or "10%" "universal mortage credit".
Currently,
the Internal-Revenue-Service (IRS.Gov)
does not have or recognize any such thing as a "universal mortgage credit".
The IRS does allow for deducting real-estate property-taxes,
and under certain circumstances, a portion of mortgage interest.
