They negate eachother. 

How about realizing that when you use the current property taxes of a property you are buying to calculate your per door profit that the following year your taxes will reset to what YOU paid for the property and will likely significantly increase your tax expense - which can take you from a positive cash flow to a negative cash flow on a low cash flow property… now you are paying your tenants to live in the property every month out of your W2 income  hoping for an appreciation play until rents hopefully increase.I could go on and on.  

As a negative, it also has the largest gap between the cost to buy versus the cost to rent, making cash flow extremely difficult without committing more equity up front.

Since I only have these 2 units for now I was thinking of using one of the free websites (Cozy, Tenant cloud, etc...).

We’re open to zero or slightly negative cash flow initially, as long as the deal provides solid equity potential.

Purchase concerns, I only know Roku, but the few apps(channels) that have this on Roku have a purchase restriction option you can turn on to eliminate this problem. 

Per CoreLogic, only 1.8% of all mortgaged homes are in a negative equity position, and the average homeowner across the US has $311,000 in equity.If anyone has contradictory data, please share.

What Are there creative strategies investors are using to offset those negative cash flows? 

That HE loan would make you cash flow negative on the first property, especially considering you are not even factoring in any repairs, maintenance, vacancy or management.

I have another one were I optioned 120 acres that just got brought into long term planning for chips act. paid 5 million for it and spend 10k a month negative..
