It's all about the right balance. 

Quote from @Renande Emile: Try to negotiate with the bank that finance the house So in the end you paid the morgage balance?

Please keep in mind that I plan to rent to college students and the free unit is about 2,000 sqft:- I went to transfer utilities and the past owners have a balance.

I’m working with them now for the first time and my taxes are 1 month late so Ive started to collect interest on any balance owed at their fault.I submitted all of my paperwork 2 months ago on the deadline as requested and I haven’t even seen a draft of my return.He’s trying to tell me since we filed an extension we have more time to file but I know that an extension gives you more time to file, but not more time to pay so anything I owe is collecting interest penalties that I’ll be responsible for as I continue to sit and wait for something from them.smh.

- Am I able to do a mortgage assumption from personal to the LLC to avoid the balance being called and effectively keep the interest rate?

The fed is going to keep a tight position as long as they can...until stuff breaks so they can vacuum up the massive amount of excess stimulus and decrease the size of their balance sheet. 

Now i have been tasked with helping my mom invest the money in her 401k account, I was wondering if there was a way to be able to take out 100% of the accounts balance to buy property with it .

I want to point out something about what @Theresa Holl said.All those things are very cool and would be nice to offer, but they would constitute significant services which will change your taxable status.So you really have to balance those sorts of special experiences or offerings.

I think you equally partially answered that question, telling the difficulties you are facing with STR regulations.this is my prescription and what I have decided to do .consider HELOC your current property, use the money to 1- add some value to your current home if room provide ( not to exceed X $ amount) you can then rent out the extra created meat to help pay HELOC2- Use the balance of HELOC to purchase another home in an appreciating market and if possible one that allows STR. use cash flow from new property still towards HELOC and just allow second home appreciate OR if you can fine a fixer upper to do BRRRR tat will even be better.that is what I have resolved to to. you can get back to me at 301-256-1578 so we can continue to brainstorm.little cent

Would the tax benefits of writing it off as an expense just be balanced out by having to pay tax on it on the receiving (PM) side?
