How to x3 and x4 the mid term

[Alon A.]

Hi guys

I see a lot of videos of people doing mid term, but i have hard time to understand something . they said the x4 their monthly rent.

When Im looking on furnish finder , i see the rents jumping by $500 not more.

example: From $2000 to $2500-2600.

So how it make sense to doing x3 and x4. because then it will be $6000-8000 per month... can you elaborate and explain me ?
