50 amp extension cord. You'll need a 6-50 adapter on the car side and a dryer outlet (14-30 or 10-30) to 6-50 adapter on the dryer side. Dryer outlets are typically 30 amps, so you'll want to crank the amperage on the car side down to 24 amps maximum.
You could also use a 30 amp rated extension cord, but it's harder to find those with compatible plug ends.
something along these lines. Then you'd use the 10-30 adapter on the Tesla side as well. This is a little bit safer because the car won't physically let you select more than 24 amps.
Just keep an eye on the dryer-outlet side for any signs of failure (melting). It would typically be the dryer plug itself that would fail. To be extra safe, charge at 20 amps instead of the full 24.
Extension cords aren't recommended for permanent use, but if this is a few months to a year while you sell your house, it shouldn't be a problem if you keep an eye on it. Careful about damaging the cord (eg repeated slamming of a door on it), and pull the dryer outlet side and look for signs of failure every so often.
