What if your tenant breaks the rules continuously and you keep getting fined.

I needed about 18-22k a month to break even.

That included sandpaper the stain the finish and all supplies a couple of pizzas.

Renting without a permit when a permit is required is breaking the city rules.

I wound up putting an offer on a house in Indianapolis after communicating with several knowledgable people including a great realtor and other investors.

It looks like a less labor intensive way to increase cash flow over the STR route but also includes structural changes to a single family home (additional setup costs) and dealing with low income tenants.  

Standard requirements for such investments typically include good credit, relevant experience, and a 20% down payment.

Every investor, my self included, wishes we would have bought sooner than we did when we fist invested.If the numbers on the duplex work NOW, given today's prices and current interest rates, then you are good to go! 

Includes a detached 4-car garage, handicap accessibility, security intercoms, a new 2019 roof, energy-efficient windows, and a suppression system land to develop.

And it's usually bleak prospects like "my landlord is an a$$', "if someone would just give me a break", or "I can afford $350/month", which doesn't even cover the sewer bill in Seattle.
