All solid-solid points. #5 hits the most for me, as I've had and have many clients that either exit as a refi or a sale, but don't consider the future value/costs based on that true future value or completion timelines. Based on Micro and Macro local market and economics the ARV can be subject to many changes come time to get the appraisal for exit and many investors slip when it comes to margin to make the refi make sense. Carrying costs in purchase and or rehab is financed, cost of capital on refi, re-recording, title, updated insurance, etc. their are many costs at play after initial funding then to transition long term unless your straight cash on the front end. The. It's just refi capital. A lot of investors think they can pull cash out no matter the payoff the have in place and the generally 75% LTARV often saddens many. Having a good game plan as an investor is key, making wise purchases, accurate budgets, holding subs accountable and to also know, yes, this may be the current ARV at purchase, but how is this market trending and what's our timeline. Did we factor in for these adjustments and what will come of cost should we transition to a hold strategy at (x) less $s or (x) more $. All I can say is I've seen it time and time again, accuracy in your estimates, detail in your work, and anticipating future costs/market changes and building contingencies in your budgets may cost you some deals but will save your investments.
