@John Persons the way I see it, waiting until the market softens is not a great strategy, since the skill set required to be successful is similar in any market condition, and there really will never be market conditions that compensate for a lack of experience. A great deal now is a great deal, just as it will be in 6 or 12 months. I'd say purchase now using the fundamentals - under market price, in need of cosmetic rehab or having some other type of problem you can fix that drives other off. If you do that and have a decent debt service coverage ratio going in, you'll withstand market fluctuations and build up equity quick also. This will really catapult your BRRRR investing forward.
In terms of how to refinance, there is no hard and fast. You need to call 15-20 local banks and credit unions to find the best terms on a commercial or portfolio loan. The first or second loan pay be good but not the best, but by the time you get to know the lending department and establish a track record, they'll accommodate you in any way that's reasonable.
