ARV is basicly a market value as of today and can fluctuate seasonally and even considering changing in economy (for example, properties around Amazon distribution center don't get sold that cheap anymore as it was just few months ago).If someone randomly trying to low ball owners without knowing the market, it's just kills his businessIMHOI think you might create a system in quite small location where you can remember all sales, rents, know it on the streets basis.

Sure, wholesalers who make inflated offers and back out, do not provide higher comps, but the activity creates more demand and does cause a net result of deals closing at higher numbers.I would argue that a wholesalers inflated offers that they back out on only affects the supply (not demand) of houses temporarily and in a way that does not fluctuate the overall supply of properties.

With a BRRRR your return is completely reliant on short term fluctuations in the real estate market since your profit is based on the ability to sell for a profit.
