@Kyle West without capital it is highly unlikely you will partner with someone for a percentage of a deal, so I just want to be upfront about that. 

I've never seen anyone attempt to actually research the percentage of section-8 tenants who inflict damages or commit some sort of fraud--all we have are anecdotal horror stories.

Diana, when you're considering how much property you can afford, but down payment percentage are you using?

2 - Using it to buy rental properties might work if those properties started out with a very high cash flow to cover the high monthly payments, however...3 - I would use it as a cash reserve replacement for holding back arbitrary percentages of rent on your other properties to cover future CAPEX, vacancies, etc... 

What percentage of tenants do you have to evict?

I have used the rental tool on BP website but I don't know what type of percentages to place in PM, Expenses, Vacancy that are accurate. 

And the state’s jobless rate remains a percentage point higher than its 12.3% peak during the Great Recession.

Yes this is just a made up example for reference to what my guess would be the possible ROI percentages when doing a good Apartment deal, as I stated in the start/title of my post "ACCURATE CONSERVATIVE RETURN NUMBERS FOR APARTMENTS (Can apply to Single and Multi Family as well):"Yeah the cash flow was the only thing I was a little not conservative on and should have fixed... 4%-8% would have been conservative id say. 

I intentionally use rounded percentages and simplified formulas, making the numbers incorrect.
