Have read and done some preliminary research on assumable loans, and was wondering if you could help me understand the hurdles that go along with it.  

From my understanding, normally with a VA loan assumption.

.- Ask the attorney if your aunt & dad need to authorize lien, or just aunt.2) Understanding your options to force payoff of the lien.- Ask attorney how you can enforce collecting on the lien when you need to.3) Getting full control of the property, while allowing your aunt to keep her ownership.- Have attorney draw up a contract to do this.Suggest you offer your dad some cash, now or in the near future, to motivate him to transfer his ownership to you.It may not work out, but you will learn a lot either way!

Of course the listed price may not be the actual rented price, but by tracking several listings for a while you can gain a better understanding of the market.

Determined to avoid such mistakes in the future, I earned my real estate license to better understand the buying and selling process.

I understand where everyone else is coming from but I do use Baselane, and I love it! 

You don't need to know everything to get started; you need a foundation to build on, and the rest will come through experience and then refining your education.You can build a basic understanding of investing in 3-6 months.

Quote from @Giacomo Matthew Degl'Innocenti: I very understand your speech but it's hard to believe the tenant has nowadays became invested of a far bigger responsibility than the landlord in making it possible to be having depicted an accurate profile also because is the landlord indeed who's on the business and receiving the money.Thanks your intervening here though  There is zero logic in any of this. 

At a minimum,  you should understand what the current zoning is and what restrictions there are.As the post above mentioned reaching out or going in person to speak with the planning and zoning department will be very helpful. 

In areas such as NYC the market tends to be a little lower, from what I understand.
