Andrew - I think you've accounted for a majority of your costs, but just a few others to consider include: vacancy factor (typically 5%), turn/over or releasing expenses, and property management fees (7-10%)  - whether you pay someone else or do that yourself you might want to include in your calculation.

You can tap into the extensive networks of property managers, attorneys, and insurance agents to get them.

Attend real estate investment seminars, workshops, or meetups to expand your network and learn from experienced investors.Risk Management: Real estate investing comes with inherent risks, so it's essential to manage risks effectively by conducting due diligence, having contingency plans, and being prepared for unexpected challenges.I hope it helps :)

I am wanting to spend the next 1-2 years managing someone's security deposit flow for free in order to learn about the current state of affairs. 

As a tenured Property Manager I meet a lot of folks that are in the real estate industry - agents, PM's, contractors, and owners.

New investor here.Thinking about end to end pipeline management for finding, closing, rehab, rent, hold/sell deals.What tools are you using to keep your information organized, clean, reportable, etc?

Use Furnished Finder to study comps, and talk to some local property managers to see if they can help you get an idea.Once you have the gross income potential number, take that and back out all of your expenses.

@Colby ValladaresI’m in Spokane, currently own 13 doors and help run our family property management business of just over 400 doors or so.

By prioritizing the data and broadening my search to different markets, I managed to achieve success.

I have been managing family property with my husband the last 3 years.
