Is there some type of PDF or template that you use as a checklist when looking at potential properties to flip or use as a rental?
If you go to tools -files there are plenty of template check lists you can use to walk a property. basically it starts with exterior-roof etc and continues room by room
When I'm going to a property I always bring a flashlight, measuring tape, and I bring my notebook which has the printed mls comps of what I'm looking at. I have my notebook as well to write down the rehab costs.
