We have put together forms that allow us to scope out properties on a walk thru and be pretty close to the final cost. 

@Diana Teng there are a LOT of potential pitfalls:(So, it's vitaly important to not just find someone that you think you can trust because they tell you what you want to hear, but you find someone that their processes seem a good fit for what you want.EXAMPLE: we do BRRR Turnkeys for clients and take numerous vides we share with them - initial, worst state of any demo, when HVAC, plumbing, electrical update BEFORE walled in, before any major payouts and of course a final walk-thru video.One thing that's accurate from all the HGTV renovation/flip shows is that you should expect and plan for surprises!

Finally, when you're talking to brokers, lenders, etc. 

Do you know how many times I called and emailed with no response untill I mention I will seek legal help and finally someone replied to me.

Eventually, after finally admitting he could not obtain a loan, he failed to return my capital, and completely stopped responding just long enough until the banks were unable to reverse any payments.

Finally, depending on the circumstances at the time, we decide how much should be held in reserve against future contingencies.

The actual cost of the turn is $2,843.17 but the security deposit returned to you is $1,650 (may change slightly on finalized intent to claim proceedings.) 

All of these are things that will give you an advantage when you finally are ready to invest.

Finally, define your long-term investment strategy, whether you’re aiming for cash flow, appreciation, or a combination, so that each decision aligns with your bigger goals.

Finally, who have you interacted with from management and what, in your mind, would make communication, functional?
