Are the 2 bedrooms in the basement legal?

And of course, I should note that I'm not an attorney so don't take any legal advice from what I say.

I bought it off market at a great deal with a conventional mortgage as a primary residence with the plans to rent it after the 12 month period has passed so I can legally rent it.

Local Regulations & Market Conditions:In areas where vacation rentals are regulated or oversaturated, factors like legal compliance and market competition can have a bigger impact than ratings.

That doesn't include legal fees and fines either. 

Can I currently legally conduct wholesale transactions in the state of PA without a real estate salesperson license?

I recommend you buy "Every Landlord's Legal Guide" by NOLO.

To navigate these challenges, condo associations need to be proactive in exploring their options and seeking legal counsel to ensure compliance and financial stability, and condo owners need to consult experienced agents on what to do, whether they're looking to buy or sell. 

I recommend you talk to an attorney to avoid making a legal mistake that permits them to stay longer.

But, It’s truly is one of the three reasons I use a PM for the rest  1) I don’t want to screen, I don’t really like meeting new people.2) I want to stay legal in my screening, notices, demands, etc etc3) They raise rents more and faster than I would and collect more in late fees.They literally pay for themselves with increased rent/fees and I get the legal and people screening for free.
