I think as long as they know their market, know what they're doing, and surrounded themselves with a great team, they should be fine. I am also a newbie and started my first flip end of last year. We're in the middle of the project when COVID struck and I was worried about what will happen next. I was constantly talking to my agent but she assured me that our market is hot and inventories remain low. I've also communicated with my contractor to make sure we were doing the best we can to stay on track. We had delays in the permits and some materials so the project took longer than expected and went slightly over budget. But at the same time, when we listed the property, the comps were higher than the ARV I used when I bought the property. On top of that, we got a solid offer over the asking price so was able to recoup the extra costs incurred.
It is still uncertain what the next few months will look like but I am still actively looking for the next project. However, this time, I am more conservative and adjusted my holding period for possible delays when analyzing deals. I think the keyword is "adaptability".
