How is everyone figuring out rehab costs for wholesale and flips without being able to see the property due to lockdown, quarantine, stay at home, or simple just seller who don't want strangers in their home at the moment? 

a lot of people recommend virtual wholesaling but it doesn't really provide details on how to solve this particular problem. I don't want to give the buyer a bad rehab estimate because I could not look at the home. 

anyone have any luck solving this issue? Thanks.
