I am assuming you mean loan to buy a property.You didn't specify the amount of the loan.But to answer your question, 18 yrs old is the legal age (in most states) so you can get a mortgage.

You might also want to look into the Series LLC, depending on how many properties you have or if you plan on growing.This isn't legal advice, just my personal thoughts on your post.

Or if I changed the locks, and they kick the door in...would I have legal right to arrest them for trespassing, etc

If you want someone specific to Carrol County find out what paper is the legal paper for the county.

Get proper legal advice for this, of course.

Shoot me a DM if you want more clarification on this - I plan on writing an article on this topic in the future, due to all the discussion I see around the topic.This isn't legal advice, but simply my own thoughts as an investor on the issue you are facing.

Legal costs will run into the thousands, so you need to be 100% certain that you are going to close on a deal with the entity/group.Your next step should be to find a property management company that specializes in the type of deal you are interested in investing in.

I would love to get my feet wet in some sort of real estate business whether it be a real estate legal assistant, working in a property management company or working in a real estate broker company, etc.

Yes, you have the legal right to enter with 48 hour notice and any buyer is going to want to view before making an offer.

I’m not necessarily aiming for the legality side of it more or less just In general.
