Definitely becoming more of a factor that will squeeze margins.

I finally got my inherited semi detached SFH (C+ working class neighborhood) ready to rent out but the attached house sticks out like a sore thumb and I believe the tenants do it on purpose as a deterrent and intimidation factor. 

But as to remaining profits - after those expenses and monies owed on the property are factored in, any monies distributed to you would count toward what would be taxed.  

It depends on a few factors.1.

No matter how much detail you share here on the forum, we will not be able to give you a reliable estimate because a lot of factors can change the result.

There are other factors to consider when looking for a market.

Passive income is generally more desired from an investor's point of view because they get a lower tax treatment than active income. 

Municipally law, rents, and appreciation all factor in to the things that make up a market.  

So I think it is dictated by your ambition, time and financial factors.

BRRR is solid but far more active so it depends on a few factors but mainly time, money and effort you're will to put in.
