Common cash flow issues in real estate arise from vacancies, unexpected repairs, or market downturns.Typically, lenders require individual investors to have at least six months of mortgage reserves.

Quote from @Todd Goedeke: @Jon Martin You are right , if you don t know how to market a property and get direct reservations you should not attempt to co-host or triple net lease a property.You fail to mention that leases on a property can be as long as 30 years.Long leases are a way to give both property owners and management companies favorable terMs.How common are 30 year leases for SFRs? 

Does anyone know if we give a Housing Authority Tenant notice that we do not intend continue renting (and provide a 90 day minimum notice).

“ I’ve noticed new people also make statements such as ‘“they opened escrow.”This is just my opinion, but I do not think it is helpful talking fancy to sellers.. 

Does anyone know if we are still required to give a 30 day notice and continue to lose out on rent that is being paid on time?

The worst part of section 8 is when they don't pay and you go to the tenant and say "Here is your 3 day notice, I didn't get rent" and they say "Not my problem, go call section 8".  

Direct mail to people in tough spots (90 day notices, unpaid taxes etc). 

You also need an online presence—this is commonly one of the most important and not done step.

With that being said, has anyone issued a 30 day eviction notice to their tenant once they take possession of their newly purchased property? 

One thing I noticed was your time to refinance (4 months) on the BP calculation.
