I wish - I'm currently renting a house for 1200 pounds/month(so...1900 USD per month) and the agency took $1000 just to take the property off the market("admin fee" - non-returnable, doesn't go towards the deposit, it's just money down the drain really), then 1 month rent as deposit, and 1 month rent in advance. So really, I spent nearly $6k just to start renting a place.

I'm really considering a mortgage, but don't have money for the downpayment. Our mortgage payments would be actually less than what we pay for rent now.

Rent pays maintenance costs, too it's just forcibly amortized and externalized. Higher-density housing like apartments and condos do have scale efficiencies reduce per-unit/occupant maintenance costs. But the difference between renting and buying is somewhat apples to oranges if you're comparing renting an apartment to buying a house.
