Also, how would I analyze the numbers for this deal, because there are various ways it could be used, either separate or possibly all together for a larger group.

Much more emotion into the deals. 

There just aren't as many deals as there used to be it seems. 

For real estate just start analyzing as many deals as you can so you get more comfortable and confident.

What made you interested in investing in this type of deal?

If all in around $435k, wouldn't she need to leave money into this deal with a projected ARV at $500k?

Since you know what you need to buy it at and an average rehab cost, I would say $50-70k for a cosmetic flip, set the ARV based on the sample you choose and doing comps and ask them if they would invest in a deal similar to this. 

Having a problem tenant and dealing with eviction could happen in any market.

If my grandmother were to pass away without deeding the trailer to me, would it be on the land owners to deal with it?

If not you will find it in the mailbox and can keep it until someone contacts you, or not.If folks change tenants and updated rental agreement are signed, we make it clear that we do not deal with divvying out the security deposit.
