I'm data driven and would love to immerse myself in IL, AL, MC specific property, demographic and investor-centric data sources the same way I've done in my previous area of focus.

I will suggest that a seminar that sells training materials only would not have helped me. 

There’s a rigid plastic type material that’s used in dairies and on farms that I’ve seen used.

As others have stated, your fit & finish goals should be guided by whether you plan to:1) Rent: tenants don't always take care of a property, so you want to use lower-grade materials and workmanship.2) Flip: higher quality on workmanship and materials is usually required.Regardless, you always want to "Maintain to the Neighborhood".

From an investment perspective, I'd look to invest in small multi-family 2-4 units with a larger down payment ~50% or more (only way to produce positive cash flow here at the moment) Investing in San Diego right now isn't driven by immediate cash flow.

The materials used for rehab werent up to his standards.

The benefit of old homes imo is that I go in and redo all of the systems and have basically a brand new house that I know was done right bc I oversaw everything.Most new homes are built with cheaper materials than the homes built in 1900.

There's some excellent relevant & recent material from very high quality individuals on this forum.

When you add purchase price, carrying costs for at least 6 months, materials, labor, real estate agents costs and taxes, do you have at least a projected 10% profit?

Are the people that give bad feedback on the reviews actually the lazy ones who sort of half commit themselves, put half *** effort in studying the material and submit half cocked deals to Jerrys buying team only to be rejected and when they dont make any money in 30-90 days just get angry and decide they will give a bad testimony on rip off report?
