Everyone says 6 months to use appraised value???
Yes…If it is a personal residence.
yes, chase bank did mine when they were known as bank one. bought the house and got a heloc in one month 100% ltv on a drive by appraisal. than three months later bought a n/o/o, with heloc on o/o, and refinanced that one 30 days later and put a heloc on this one, chase as well. at that point your done with them because they only allow one n/o/o. 
i believe first franklin does them also with drive by appraisals.
Aegis Home Equity does them, Charter 1 does them, and Pemmtek does them I believe.
