Built out the basement into a 2 bed/1 bath unit Lessons learned?

So you have a log on your Sawmill bed. 

It's not really a fact of the world but a risk a real risk correct but its a what if, and if I laid in bed after successfully setting up an Airbnb arbitrage and so far have success and just think about what if this or what if that, it'll only slow me down. 

My priority is getting as close to cash flowing as possible with minimum investment on a 4 beds 2 baths but I'm also thinking about appreciation because you never know when you'll have to sell...

Couch, lounge chairs, bed, rug.

I wouldn't be able to sleep at night knowing that I had people in my properties that had mice or bed bugs or cockroaches. 

But a bedroom or a bathroom can be easily qualified in terms of dollars (I usually see $4,000-$5,000 allotted for differences in bed/bath count).Truthfully, if I can't find easy comps and if I can't make it easy for the appraiser to agree with the value I'm looking for, I just don't buy it.

My unit is a 1090 SF, 2 bed 1.5 bath townhouse.

@Marco Teixeira I'm looking into it as well, the main two issues I'm trying to solve are that not only you have to find the property but be conscious about to which city hall that area belongs, that makes a huge difference in time frames if you want to license it as senior living, the other thing is scale, it's more management intensive (staff 24/7, doctor visits, nurses, food, etc...) therefore if you don't have enough beds it might not make sense, you'll end up having to charge too much per person for you just to break even, that being said there is definitely a HUGE demand for it.

Furnished common area, furnished each bedroom with a queen bed, a dresser, a desk and a chair, then we listed on every platform that I can list and I paid every platform for their premium listing.
