For investors, these are really the bread and butter for rentals.D: Run down properties in bad areas.The area and the property can be described separately.

I prefer class B and C MFH properties, such as 15, 30, 50 unit apartments. these assets perform great in up markets and provide decent cash flow protection in down markets as people who lost their class A homes in a downturn, move into these apartments. it the bread and butter asset class.

@Christopher SmithFrom one active duty Air Force Member to another, one multifamily investor to another - quit whining and suck it up butter cup. 

To a broker/agent selling regular properties with buyers for home owners they might see it as quick additional income while they do their bread and butter business.

I would keep your money in your Roth so you have some diversification and aren't 100% invested in RE.While RE is my bread and butter as well I max out a Roth yearly and a work 401k as well to create additional truly passive income.The other thing not mentioned is while a Roth is a home run as far as taxes go, a traditional can still be beneficial to the RE investor who has W-2 income of under 150k as with a traditional IRA you can deduct the 5500 against your  taxable income allowing to maximize the 25k passive loss allowance.

The quick wipe the wall, slap the tile on,,,,or the right way with thin set and each tile back buttered???

Most bread and butter flippers that I bump into are targeting 10-15% profit. 

Just like @Patrick Drury mentioned, by bread and butter is cold calling.

Over the course of a year my wife and I fixed it up, rented to friends, ate peanut butter and jelly, did everything we could.

Thanks Anthony, we'll have to the bricks sometime too.There ya go Philip, that's the way to butter up the instructor, LOLI sure don't know everything in RE, I just don't have time for that.The goal should be know enough about various aspects and then realize you don't know and then how to find what you don't know.
