This article walks through the steps in a cost segregation study.WHAT INFORMATION DO I NEED TO PROVIDE IN A COST SEGREGATION STUDY?

I'm looking at monthly cost to seller vs. anticipated rental income, purchase price relevant to the ARV of the area and interest rate, balloon, etc.

I consider inventory rates, price trends, unemployment data, population growth, job growth all to be relevant to where a market is at and where a market is heading.

I was considering reading J Scott’s “The Book On Estimating Rehab Costs” but wasn’t sure if the information remains relevant 6 years later given how pricing has changed since then. 

@Melvin Lamont Evans Welcome to BiggerPocketsThe search function can help you find some relevant informationhere is an example https://www.biggerpockets.com/forums/88/topics/1049073-my-fi...

here is a good relevant read https://privatesyndication.club/articles/can-an-rv-park-be-a...https://Privatesyndication.club  may be a good resource for you. 

@Garrett Brown may have advice on where to start and who to start with as he experience in glamping that is relevant.

As lenders, well issue a prequal/preapproval letter if we've analyzed your income, assets (bank and brokerage statements to establish that you have the liquidity to afford the down payment, closing costs, and reserves), review credit of the guarantors, review the relevant experience to ensure that we're not throwing our money away on newbies that are wandering around in the dark, and have put together a reasonable plan of attack for the project.

I was graciously invited to a REIA retreat to go over the future of REIA and how to stay relevant in this information time we are in.

I would say that most of the information in that book is still relevant, but many of the numbers will be outdated.
