we are an investor with MBD which is currently going through the legal process and I've been a current investor with TechVestor for about 18 months with 100s of thousands of dollars invested with them.

Hello  my name is dozar  from chambersburg pa , I own a duplex  and plan to buy one property each year  for 10 years through house hacking method. 

The rest have a combined worth of about 1.5 million but aren’t owned free and clear yet.All Properties are collecting rent and generate about $16,500 (profit) a month in Cash flow after mortgages/expenses.

I got a 6.25% rate, and even before refinancing I am now cash flowing 1K/month because of the STR.  

sell the 3 family and buy 2 more properties with it that dont cash flow?

He "doesn't want to scare off his tenants if the deal falls through." 

All other assumptions look good to me, but I must admit the cash flow per month wouldn't meet my criteria for the investment - it's lower for my returns.

I am considering buying a property in the Myrtle beach area since it seems like it’s an affordable are with good cash flowing properties but it seems like the crime rate is above the national average.

The rate alone will be above 9% and in most cases its stops the property from DSCR cash flow ratio of 1.00% or higher depending on lender.

Not all properties will cash flow, especially in some areas.
