On the contrary, if an exec board has 50-100 years+ of experience they likely have seen some adverse economic cycles and know how to pivot in such environments. 

To overcome this, consider widening your search to surrounding areas, exploring different property types like condos or townhomes, networking extensively with local real estate professionals, and thinking outside the conventional options, such as renovating older houses or adding accessory dwelling units (ADUs) on your family's property.

If not, what strategies do you use to overcome this?

The market will likely rebound down the road, if it does, losing 30% means you need to do very well with your new investment to overcome the loss.  

I'm unable to find a sample adverse action letter with Zillow as the screening/consumer reporting company.

Having a mentor may help you overcome obstacles and offer advice and insightful advice.Remember, every successful investor started somewhere.

What challenges did you face, and how did you overcome them?

You will have to get your ejectment order to be completely safe, or pay off one of the heirs to let you take possession peaceably, and then wait out three years of exclusive and continuous possession (which means someone actually on the property using it, usually a tenant) before you have adversely possessed it and "cured" the void tax sale.

I think the best way to overcome analysis paralysis is to align yourself with an agent you like and trust and who is well-connected so you feel confident you'll have the support you need to close the deal and get off to a good start. 

Thank you,Rami Risk/reward, it’s one of the only areas in region you can get a really good deal vs peak prices, but there’s obviously the risk it doesn’t come back or that it gets worse, I’m slightly risk adverse & crime is something that I have no control over, so I’d probably not be a buyer there but the prices certainly are interesting, if I was included to invest in a down home in dc I’d probably look more Michigan park/riggs park area.
