First of all, you need to figure out the different between non-O and non-OA. With the non-OA you don't have to tie any money up, you use money in your home bank account to qualify for a 1-year multiple entry visa. The caveat is that the requirements are higher than the non-O, and you also have to have mandatory health insurance.
With the non-O, you can show money in your home country for the initial 90 day visa, but then once you get to Thailand you have to quickly open the bank account and transfer the money to use for the 1-year extension.
You don't need any type of visa to sign a lease. The landlord doesn't care what type of visa you are on, they just want your rent payment.
If you are even considering elite visa, and the crazy expense of that, look at the LTR Visa first. If you can qualify for it, it's the best visa available currently.
