How detailed are you wanting to get with your rehab estimate. Ive not heard of either of the products you describe. High level, just take in to consideration about 15 items in 'chunks'. More detailed, I have mostly relied on previous rehab jobs to estimate & or, what I know particular contractors use for their bids...or, for more specialty items, price those by the prospective sub contractor that i might have do the job. (i.e. carpet, flooring, granite?, window replace, painter, foundation, electrical & Plumbing issues if they are very large.) I imagine this is not what you are looking for - but that's how I do it. I usually dont bring in trades until I feel good about the deal after running my estimated (guestimated) numbers, and I feel the seller will be on board with my offer. I never want to run my subs or contractors ragged.
there's my method, for whatever that is worth! LOL
