@Jordan Moorhead house hacking is working well in this environment.

If you bank at a retail bank it's likely that you could pull a cashier's check to provide  certified funds.As to the wisdom of using other people's money (that you are solely responsible for) you'd better be comfortable with repayment even if things don't work out as planned.

At that point you can decide if you want to max out on your first property or be conservative and just borrow what you feel comfortable based on the payment.

Caution that these repayments generally cost more in the long run and the strategy would be to refinance again in a more favorable interest rate environment. 

Get out of your comfort zone.

Enhance the outdoor space with a BBQ grill, comfortable seating, and a dining area.

Its certainly hard to cash flow significantly in the current environment (high rates, high values etc) - I tend to think though that just "doing" a first deal even if it doesn't make too much is valuable versus getting stuck in analysis paralysis - the learning from the experience of actual doing it generally is 10X + even a ton of courses, info, spreadsheets etc

I knocked on the door and stepped back a little ways so she would feel more comfortable coming to the door.

It's best to discuss this with potential tenants before they sign the lease to see if they are comfortable with having cameras on the property.As for providing internet service, it could turn into a headache.

In the end, it's your decision based on your comfort level.If I (my risk profile) were you, based solely on what is above, I would not go for the 3rd property at this point.
