Perfectly legal, no hassles.

And don’t overthink—your first deal doesn’t have to be perfect; it just has to get you in the game.You’ve already taken a big step by asking for guidance, so keep that curiosity alive and stay consistent —let’s crush it!

Quote from @Sakib Khan: Hey everyone,I’ve been toying with the idea of jumping into the world of rental property investing, and I thought this would be the perfect place to ask for advice.

No deal is perfect, and anyone on these forums will have different investment objectives as you, but you will typically get some things to at least think about before moving forward.

Chris summarized it perfectly.

I got so lucky - the first 3 years, during the depths of the pandemic, I had a perfect tenant, no problems, even during the storms. 

Your approach to finishing the basements in order to extend the number of years a tenant stays in that unit makes perfect sense!

Not considering it will take years of perfect rental with no vacancy or capex just to “break even” with where they are today. 

When you have things that you do not know how bad they are until you open up pandora's box, it is hard to perfectly predict the cost.I'd be happy to have a more in-depth conversation if interested. 

Finding an investor-friendly agent is key and they should be able to help you with 1-4, I'd say talking about those questions you asked would be the perfect thing to ask any potential agents you interview!
