I have identified properties in a particular area I want to target and want to reach out to the property owner to see if they would sell.

I am targeting duplexes on the same street.  

@Nathan Gesner  Don't believe everything you read, especially on the web. 

Here’s our OPINION for the Metro Detroit market (use as a template for your target area!)

I have some web design skills (I'm an engineer, so easy to learn new programming languages) and I'm currently testing my new system to manage the tenants.

They should not have been this off and you should always use the worst-case scenario as your target number when you are doing a flip or BRRRR.If I were you and a sale wouldn't net enough, I would do mid-term rental there instead of long-term rental so you can earn more, but still not have a ton of tenancies.

Here’s our OPINION for the Metro Detroit market (use as a template for your target area!)

The towns you're targeting—Rochester, Dover, Farmington, and Milton—offer great potential, especially for flipping and buy-and-hold multifamily investments.

Any insight on neighborhoods to target for LTR, or lakes to target for STR (open to non lakes as well).  

They don’t effectively target motivated sellers.In fact, the market is saturated with these outdated and inefficient approaches.
