There will be significant hurdles to easily obtaining a cheap and small apartment. Most want pay stubs, credit checks, previous residence, etc. There is a definite potential problem here if OP truly has the cash, but isn't actually generating income. That can cause him to disqualify for housing like apartments - which sucks, so long as he really has the cash. Why need to show you are bringing in income when you have a nest egg big enough to pay rent for years?
For the relatively sound reason that a bank statement really says nothing about what sort of expenditures the account is responsible for. In fact it basically proves nothing. I had an extra hundred thousand dollars in my bank account just last month, through various circumstances, but it was only nominally mine to spend. Additionally, tenants with jobs have likely already passed through character checks, criminal record checks and so on. Tenants with 100k possibly haven't. A holdover in an extended stay motel is the answer here.Why need to show you are bringing in income when you have a nest egg big enough to pay rent for years?
