I was thinking since potential clients are afraid of meeting and maybe looking at available properties would it help to put more emphasis on  creating really professional photos for your properties and maybe a video walk trough..   People will be more comfortable to see a great online presentation and have an better idea of the property the would like to buy after this crisis..  I been doing real estate photography for AirBnB since the beginning and that was the only marketing tool the invested in, the basically covered for the first 8 years all the photography costs for hosts !  Without any advertising the got so big :~)     Stay Safe but Productive !  Adrian
