Ross Hamilton knows full well the kind of people that promote their garbage on his site.

There's now a garbage can cover leaning against the house over them.

By me in WI in Kenosha it used to be $50k for a 2 unit now its $120k for a garbage one needing 40k in repairs or $170k+ for a good one that rents $1600 with tenants that get evicted and dont pay often LOL We have some tertiary markets like Elgin where you can get decent tenants and $5000 gross out of a $450k 4 unit it still works but is getting harder forsure. 

Who pays for garbage?

I used a 5% loan with 20% down, $2900 in rents, 10% management fee, $150 a month for water,  landscaping and the garbage bill.

A lot of times, depending on city ordinances,  landscape overgrowth, on the home, on the roof, on the sidewalk, garbage near or around the home,  just to think of a few things, can result in violations and fines from the city.

I leave out a lot of the other “maintenance nightmares” like garbage disposals and dishwashers, but find ceiling fans to be low maintenance.

Any calculator/formula is subject to GIGO....garbage in, garbage out.  

Pour the grease into that and once the grease has set and the can is full (ie don't use it once time, keep adding to it), put the can in the garbage. 

I also love that you take the time to sell and donate many of the items instead of just throwing everything in the garbage.
