I save them because I look up who sends them so I know who the players of the game are.

I personally would keep them seperate unless your broker is getting a cut from all your deals..you can disclose to your client that you are also a real estate agent if they need your assistance you would be capable of helping.

The guarantor is pretty much a STAPLE player when it comes to business lending.  

But before we dive into the formula, let's meet the players in this real estate drama:Rental Income: The star of the show – this is the money you receive from renting out your property.Mortgage Payment: The giant elephant in the room – this can be a hefty expense, but don't worry, it's worth it in the long run.Property Taxes: The government's cut – just like paying taxes on your salary, you have to pay taxes on your rental property too.Insurance: The safety net – protects your property and your finances in case of natural disasters or accidents.Repairs and Maintenance: The handyman – because things break, it's just a fact of life.Utilities: The energy boosters – keep your tenants comfortable and happy.Property Management Fees (if applicable): The middleman – if you don't have the time or patience to deal with the day-to-day responsibilities of being a landlord, this is the solution.Now that you know the players, let's get to the formula:Actual Cash Flow = Rental Income - (Mortgage Payment + Property Taxes + Insurance + Repairs and Maintenance + Utilities + Property Management Fees)It's simple, yet powerful.

Meet the local players.

If you're a serious player who buys properties off MLS regularly, you should have no trouble finding a realtor who wants to work with you.

In terms of established players knowing more about a houses condition - that comes from experience and preparation.

Real estate has this capability due to leverage and ability to extract initial investment.  

Before starting to process the new month payments, the prior month is checked again for any glaring errors, and then the month is ""locked", preventing any changes to that month, at any time in the future, by anyone.I do not know of Appfolio's capabilities, but any competent PM should be providing copies of all PAID invoices with the monthly reports, in the month they are paid. 

@Samuel Nyu I would find a property manager ASAP because it appears you may not be ready or capable of being a landlord.
