My biggest piece of advice is to CHOOSE YOUR MARKET WISELY.

I meet a lot of clients on BiggerPockets and internet advertising.

Are others persuaded by the argument, made by @Jason Hartman and others, that the pandemic will accelerate the trend of people moving away from high-density living in the biggest cities and into more single-family homes in the middle of the country where prices are cheaper and the risk of a virus spreading is lower?

She's since become one of my biggest supporters.

Our biggest challenge to that right now is covid-19 obviously, we still can’t meet with clients as agents yet and it is not really advisable to get together in groups.

My biggest suggestion for a screening tenants would be RentPrep.com.

Any opinion what property might take the biggest hit if there is a drop in prices.

So my biggest concern is that by the time the work ends up getting done, prices will have dropped (including my ARV) and lending will have tightened so getting money back out will be a much slimmer chance. 

Mindset is one of the biggest things to overcome.
