My initial plan was to purchase enough rentals to help offset some of the mortgage of my future home in LA.

I've helped a few people with considering modular rebuilds in fire areas and there are some modular and manufactured companies that I work with with that have some specialization in the area. - Orbit is one.

I am just starting out so any help will be greatly appreciated!

If you'd like some help with the investment property aspect of this I'd be happy to take a look.

That helps a lot.

I would also pull out enough cash to go and buy more real estate to help increase cash flow.

Thank you for your help.

Setting up a bank account at a local bank or credit union could help grow your business in the future.

I made the mistake of listening to realtors who pushed me towards using Anderson 100 windows on a few for sale projects citing the name recognition will help sales.

A self analysis of these items should help you decide whether it makes sense to proceed with the improvements or if perhaps you are better suited selling the building as-is and re-invest your capital and time into projects that better align with your core competencies.
