@Andrea LeeRecommend exploring as many sources as possible to get referrals AND cross-reference them to get as much accurate information as possible.Check out NARPM.com, BP’s Property Manager Finder (BiggerPockets: The Real Estate Investing Social Network), etc.Also, encourage you to learn from the mistakes of others - by reading posts here on BiggerPockets about owners not having their expectations met by their current Property Management Company.

That being said, here’s what I would recommend for a thorough DD process:-Build a plan in advance (setup a spreadsheet, meet with the team, etc)-be prepared to take a lot of pictures -document notes with each room (we use notes on Apple and share it with the team)-align the team on standardizing information (example: what does “bad” mean, what does “okay” mean, etc - everyone looks at things differently and you want to make sure the notes are accurate during your debrief)-bring in professionals for things you can see, like sewer lines hope this short list helps! 

Quote from @Michael Smythe: @Marcus Gonzalez you'll need a general contractor with accurate numbers.With no experience, you'll probably need 25-30% down for a spec home construction loan. 

Maintenance/platform fees/cap ex/rental insurance - $2,000Income - $10,800Expenses - $12,532Is this somewhat accurate?

Is this accurate, if a property is owned by investors and constantly being sold and bought that's a warning sign? 

You cannot afford to waste time.Just make sure your numbers are accurate otherwise you can create a bad rep among real investors. 

I asked Gemini and it pumped out some responses, but I know literally nothing about this so I have no clue how accurate it is and it definitely also recommends consulting with a lawyer and other experts in this arena.

If the software is not simplifying your life or making you more accurate, you shouldn't use it.

Imagine you bought a property for $2M.The land (excluding any structures) is valued at $400K.Since land is not depreciable in the eyes of the IRS, we subtract the land value from your purchase price to get your depreciable basis.Your depreciable basis is simply where a cost seg engineer starts from when allocating your eligible assets into either 5, 7, or 15 year property.In the scenario above, your starting basis would be $1.6M since your basis = your purchase price - the land value.Having an accurate land value is essential to getting your depreciation/bonus depreciation calculations right.This is the starting point for any cost seg study that you do.
