You don't, but if you are saving (not spending), access is a none issue. The money is still there (in equity) and YOURS.
Access to that money will be available after you sell the house anyways. And if you save it up front, well, when you sell the house and you are upside down you are blowing those savings anyways. NO DIFFERENCE
Besides, you are already "financially responsible" and saving on regular basis anyways right? To replenish your savings is no big deal.
And let's be real here, any savings you might have will be blown to BS things anyways....furniture...unexpected repairs etc.
That's because you weren't ready to buy a house NOR were you financially responsible and have good financial habits to save for a proper down payment to BEGIN with.
Here we are, 7+ years after the housing economy crashed because people weren't financially responsible, didn't put down enough money and got into shitty loans.....and people are still recommending buying a house with shitty loans and no financial responsibility.
Expected. I didn't expect people to change.
Yes it's HARD to save 20%, yes it's hard to buy a house. IT'S SUPPOSE TO BE. Stop buying into an illusion that everything is easy.....you will have 1 million people selling you that illusion......but time comes where the reality kicks in, and all of those people have already disappeared with YOUR money. While you are ON YOUR OWN.
