Based upon the cost seg studies of my clients, a building will typically yield 25-30% of the total cost that can be segregated into personal property and land improvements.

And how far back in time would you consider someone a client?   

The attorney tells the client to keep quiet.

I was quoting pool prices for my clients several years ago at approximately $40K (basic package 12'X24' including screen enclosure and paver deck) and then they doubled and more after COVID.

Most of my clients:1) Put 20% down for a conventional investment loan.2) Put 10% down for a second home loan3) Something else, either hard money, DSCR, or portfolio loans.These are the most common ways. 

We pride ourselves on managing our client properties as if they were our own because that is how our company was founded.

In tight inventory markets like Boston, I encourage clients to clearly define their purchasing criteria, start looking, and then be patient.Some of the best deals I have seen or experienced personally happened during unusual circumstances.

Start small with a single property to learn the process and scale as you gain experience.This post does not create a CPA-Client relationship.

but I had a few thousand transactions in my experience bucket and I did it for one client only..  

@Nathan Frost typical for Detroit, that's why we offer our clients several security options, including removing & storing mechanicals when vacant and then reinstalling day tenant moves in.What makes you think the seller will install new mechanicals?
