<human>: Can you condense the text into a few key points?

Hello again /r/personalfinance! I am moving within the next month and have found a large condominium complex that is offering a great deal on their rent as well as any application fees. It will be my first time renting an apartment under my name so I want to be as thorough as possible. They are at low occupancy and can flex their prices a bit which is a nice bonus. To my knowledge, the development is well managed and I have heard positive remarks from them.

However, they have raised two red flags so far in my application process. They may not be a huge deal, but this is my first time renting in my name and I want to make sure I'm not leaving any loopholes open to be taken advantage of.

Firstly, the reduced price for the application fee and lowered rent have not been distributed to me on official letterhead. They were only discussed in person and over the phone. Would it be better to have an official statement from them? I have sent them an email this morning requesting that I have something tangible, either hard copy or PDF that I can keep in my records and budget.

Secondly, and also my main question, is that they have requested my proof of income to rent from them. But it just seems unsecured in how they want me to provide it. They just want a PDF copy of my pay stub or financial information in a regular email to their yahoo account. The management doesn't seem to have individual accounts, just the single yahoo address for the whole development.

Any advice for providing my financials like this to a single email account? Would it be better to bring a hard copy of my information? Or am I overthinking this whole thing?

Like I said, I'm new to renting property and want to make sure I'm being cautious enough.

Aside from that, are there any other tips or things to consider while talking with them? Thank you for any suggestions! :D
<bot>: New to renting property, the development is asking for my proof of income. Do I send them to their single @yahoo account or bring hard copy? Am I too paranoid?
