It will just add expensive fees to your deal that you don’t need.

It's simple enough to make a row for income, and another for expenses, and then subdivide those expenses, and add them up in the total expenses cell and then subtract the gross income from those total expenses to get my net.

Our biggest expense was replacement vinyl siding, which costed around $40K.

You already paid for it now so make sure you really get your money's worth. 

My Expensive Lesson)My first rental with REI Nation turned into an absolute money pit.

Going to try out PayRange, the Shine Pay is slightly more expensive and the one quote about the 20 units appears to be from shinepay as it is the only qoute they ever made... not sure which is better but both look like good options

And that’s before factoring in selling costs—commissions, taxes, and closing expenses.

You basically own 3 paid for properties. 

Quote from @Jeffrey Bourque: Hello All, I am new and this is my first attempt at purchasing a property with the intent to create monthly cash flow.The property: Triplex Listed at $140,000 - Total monthly rent income $2,150 - Tenants want to stay and are all willing to sign new leases for 3 years - 8 beds 5 baths and 3,500sqft livable space on a 4,800sqft lot - Heat and electric paid by tenants and water trash paid by owner $180 month - I have managed to talk the selling price down to $105,000 with a kick of $10,000 for closing and commissions so $115,000 all in - Building is in fairly good shape according to pictures and questions but have not done a inspection yet - some general maintenance repairs are needed according to the seller but nothing that seems to bother the tenants. - Taxes are on the higher side at $6,000 yearMy Numbers: $115,000 putting 20% of my money $23,000 and finance the rest with total expense of $1,834Monthly expense numbers: Future Maintenance 13% $273 - Vacancy 5% $105 - Property Insurance 5% $105 - Property Taxes 23% $500 - Property management 10% $215 - Office/Travel/Legal 4% $84 - Mortgage 26% $552 - Monthly Cash Flow - $316 per month or $3,792 per year so Cash on Cash = 17%I think this looks like it is a deal worth doing and I also believe I can bump the total rent up by $50 each tenant which I think make it even better.

Rent is paid on time, and no problems with the general inspections at the beginning.
