I don't know your size but if you look around, you can find a bike somewhere on clearance with decent components. You'll have to deal with getting one sight unseen, it may not fit, possibly having to put it together yourself, maybe the wheel bent in shipping etc but that happens with any mail order bike. Other options? Like others said. LBS or take your chances used on CL/facebook.
An example
https://www.amazon.com/Mongoose-Mens...1ID?th=1&psc=1
The current price is $677, it will probably change back to retail price > $1000 as soon as 1 or 2 sell again (Amazon pricing does that on bikes). In theory, Amazon shipped and sold offers free setup/assembly at a local shop.
It's not a "Walmart Mongoose", the components are great and above what is on any bikes at that price point if you can get it for under $700.

If you dig around somewhere you can find the size, the wheel (29 or 27.5) and a price you want somewhere. How much do you want to spend and how much do you want to look
Is $700 to high? There is always the Diamondback overdrive on sale and a number of bikesdirect bikes in the $300-400 range. Nothing great but could serve you well for years and 1/2 the price.
