Meaning we never get big red flashing signs of 'buy here!!' 

Hi JordanHappy Holidays to you as well, You sound like you are new to having interest in Seller Finance which could be a red flag for those owners who's looking for experienced property management personnel (young or older) which has no barring on age.

.- In Red, you can see which "Map sheet number" you need to pull up if you want to look at addresses along a particular street. 

I am not red or blue. 2) I truly feel bad for people going through hardships right now.With that said, prior to COVID, real estate prices were sky rocketing.

A few neighborhoods that are walkable to the MARC train that goes to Union Station/metro in DC are:Mount Vernon and Station North (Penn Station)Ridley's Delight, Sharp Leadenhall, Otterbein (Camden Station)This isn't an exhaustive list, but I've seen some multi family homes over the past 12 months in the bolded neighborhoods. 

They replenish their $500 red serve as if money falling down from trees

I will attach a picture, so, if possible can someone tell me if they see any red flags on the requirements.

The Red Hawk or Crowne Hill area are commonly the most desirable

I see it as a red flag.

The fact they are even asking indicates they are probably living paycheck-to-paycheck, whichis a red flag.
