then you need to find a good place to do this

how do you calculate the 20% eviction rate?

say you got 3 before, so you got 15 houses? Or do you mean per year 20% so you got three years cases? then you got 5 houses.

If you got 5, or 15 houses, it it hard to claim you are investing, correct?

If define the rate as: Total Cases / Total Houses X Total Years, then it is very hard to get 20% rate.

For example, 1 / 10x5 = 2%
