I'm starting the process of looking to buy a house. My partner uses a power wheelchair and anything we buy is going to need to be accessible or modifiable. So I know we're looking for a ranch, probably 3/2 at most is what will be affordable but I'm finalizing my pre-approval now.

That said... I'm almost 40 and I've never bought a house before. What are some things I need to know when looking at a house? I have a realtor and we're looking at our first place tomorrow. I'm bringing a measuring tape because the accessibility will matter.
But I don't even know where to start and what the normal questions are!

I graduated in the spring and spent the last few months at home with family. I'm hoping to find an apartment/job in a major US city working as a legal assistant or paralegal.

I've never rented before, so I have questions, but due to circumstances related to the ones pushing me away from staying at home any longer, I don't have any parents or older siblings to ask for help, so I'm hoping to crowdsource wisdom here. I have specific questions, but also happy to hear any general advice for someone renting an apartment for the first time.

Some relevant context:

• Studio apartment is nonnegotiable. I don't know anyone I trust enough to be my roommate. If that weren't enough, I'm one of the only people still wearing a mask and trying not to get COVID, so it's gotta be a studio for me to be able to relax.
• I'm looking for a walkable neighborhood and good public transit in addition to affordability, so really looking at Chicago and Philly right now.
• I love to cook, but I know studios often have really lackluster kitchens. Hoping to find one with a usable amount of counterspace.

Those questions I had:

1. If you offer to pay a landlord the cost of the lease in full, is it typical for the landlord to waive the requirement that you provide proof of employment, or if you asked them to waive that, would they be likely to say yes? I would really like to take some time off, and coming home was intended to be that, but toxic family means I've just been stressed the whole time, so being able to get a place without needing a job right off the bat would be a fantastic setup to make sure this new start goes well. (If I save up part-time earnings for the next 2-3 months, I'll have enough to pay a lease on a $1200 studio in full, furnish it with the necessities, and feed myself.)

2. Recently I realized that when apartments are listed as unfurnished, that means no bed or mattress either. (I kind of see now why futons are a thing.) How do people usually address this issue? Do you buy a mattress and bed frame with the expectation that you'll take it with you whenever you move out to the next apartment?

3. Since I don't live in the city I'll be moving to, I most likely won't be able to see the apartment in person before committing. Any particular ideas on how I could handle this or what I should be wary of? I've heard of services where you can pay someone to show up to a tour and video call you so you can follow along (https://www.gandertour.com/). $50 doesn't seem too steep, but I don't know if that specific service is trustworthy, or if there's a cheaper or simpler way to deal with this.

Those are my questions, and like I said above, any advice not 100% related to these questions is welcome too!
