I’ve been listening to biggerpockets podcast, reading book, blogs and I would really like to get started... don’t really have a lot of money. 

You should check out “set for life” by @scott trench.Really good book for anyone starting!

BP podcasts, speaking at established companies, writing a book, SEC investigation, FBI review etc do not make people honest.

It's just easier to book that the entity purchased $X of paint as one expense.If you appreciate the details and like a high degree of organization, it's not at all difficult to keep impeccable records.

It’s not only note investing but I see a lot of posts on here and some of my favorites are:1. what book should I read to buy a 100 unit apartment building” when they have never been a landlord 2. how do I subdivide and develop a parcel of land and how much should I budget when they have never owned anything. 3.what should I do with my $100k. 4.

They make these in all the standard sizes people expect storage units to be available in.There is/was a huge need for storage space in my neck of the woods and I came "this close" to buying some shipping containers and doing exactly what you are thinking. 

Broker/my mentor is suggesting to be realistic, and present a price that reflects what the new buyers' expenses would be.Is it more of a standard practice to calculate the price based on current owner's expenses, or future owner's expenses?

Do you think learning by doing or books and podcast here to learn real estate investing?

I consume loads of information now: podcasts, books, blogs.

@Oles Street A good way would be to learn about what you want to do first by reading books and listening to podcasts, and networking with experienced investors.
