No one will prevent you from following your heart and providing help, be it financial or emotional, to those you feel are in need of your assistance. 

One of the challenges especially with your first purchase is not to become " emotionally attached " to your property . 

I’ve had tenants get dragged away in cuffs just because they were too emotional.

As to analysis, be objective and not emotional. 

Once the seller is talking, you stop and listen to what they are saying (pay attention to the things that aren't said outright).An "absurd" or "insulting" offer to you may not be considered so by the seller.Go into the negotiations with ZERO neediness and zero expectationsStay level headed - even when the seller is getting emotional.

Hello,If my rental contract said no dogs allowed which tenant agreed to and later on a few months after the tenant moved in decides to get a emotional support dog because of the coronavirus, can they do that?

It was lots of motivational rah-rah, outlandish public displays of emotion, but really not much content.

@Fern Vargas My gut is telling me to walk away too, getting too emotional on this one due to location but the numbers aren't adding up.

You need to not be emotional about it and not feel desperate to accept someone. 

Maybe they are emotionally attached to the house and they don't want to leave.
