Hey @Nigel Ford, I think Brandon from Bigger Pockets did a great job breaking down this subject via video.

Over the years I've had 100's of investors reach out to me about properties and after I give them the info such as a full video tour, analysis and even a 3rd party appraisal they will ask a question like "is it turnkey?" 

I read a few real estate investing books , YouTube videos , podcast and I think it’s time to pull the trigger .  

I am 23 years of age and I have absolutely no experience in real estate other than the videos, forums, and research I’ve done in the past month.

Watch some videos on youtube and it should give you a decent foundation to build on.Here's a quick use case with some easy numbers:10 unit property - Purchase price $1,000,000Annual income = 10 units x $1000/unit/month x 12 months = $120,000Using 50% rule - Expenses = $120,000 x 50% = $60,000NOI = $120,000 - $60,000 = $60,000Property was purchased at a 6% cap rate ($60,000 NOI / $1,000,000 PP)---Value Add:Increase Rents by $50/unit/month:Annual income = 10 units x $1050/unit/month x 12 months = $126,000Decrease expenses by 10%  - Expenses = $60,000 - 10% ($6,000) = $54,000.NOI: $126,000 - $54,000 = $72,000Assuming market cap remains at 6%New Value: NOI ($72,000) / Cap Rate (.06) = $1,200,000

My wife will take her phone and take videos of the house.

You watch the videos of working Mom buys 15 homes in 1 year to the guy out of Atlanta went from a 9-5 to 300 doors in 6 months and now full time investor.

Google "velocity banking" and watch one of the shorter videos on it. 

I’ve been listening to a ton of podcasts, reading books and watching videos but it’s hard to know exactly where to begin or what I should do so I’m seeking advice.

You'll also be able to find links to his website there where I believe he gives out some of his scripts.Youtube has tons of videos utilizing cold calling scripts and I'm sure many of the big names on there will have some kind of free scripts you can download or sign up for.Best of luck to you moving forward!
