Quote from @Luca Perinuzzi: I'm studying for my real estate license, and plan to primarily work with investors once I'm licensed.

Here's an article with additional FAQs on cost segregation studies that you may find helpful.

I’ve been studying real estate for the past few months, reading books and absorbing as much as I can.

I go in---check out the house, study the area, etc., and rarely present an offer.

I’d personally prefer the one opposite the beach as I think the other lots are too far but I haven’t made a study on hotel clients.

Study up on warrantable vs non-warrantable condos.One idea I think for a fresh grad, is to find a great RV park operator. 

Study more being a landlord and the importance of agreements and especially sec 8.

This includes meeting with the city, engineering, conducting required studies, plat maps, etc.

Navigating these delays and organizational instability proved to be immensely challenging.In my own investigation, I discovered that Farraway SG emerged as the new entity managing the loans, with its LLC tracing back to Tel Aviv.

For the first part of your question even if you were working with a realtor, I don't personally know many that have a true pulse on rehab costs and I wouldn't make any investment decisions based on their rehab cost projections.My suggestion would be to study how to evaluate the Big 6 rehab costs: roof, siding, windows, HVAC, electrical, and plumbing.
