At this point in time, to give y’all an idea of what I’m doing(I’m from Texas), I’m wholesaling, have a dialer in place qualifying leads, I follow up, I’m in the process of creating an LLC just for basic RE income(operating company), and I’ll expand into either a parent LLC or S-Corp with underlying LLC’s with land trusts that have properties in each of them, along with a lush umbrella policy.

I am currently living in my parents’ old house and not paying rent.

The rest is a mystery.For example: the fee for a rental with a single filer with no activity other than three rentals is going to be very different than a MFJ filer with two high income W-2s, portfolio income, three kids (child tax credit and childcare expense credit), a Schedule C business, and three rentals. 

I own a multi-unit apartment building with my parents and they are looking to sell their share.

I'm 19 and my girlfriend of 3+ years is 21 and we both live with our parents.

OK, so in WI if you bid on a first mortgage, all other liens are "foreclosed out" with the exception of government liens and often you can get those removed if they are not for the property, like back child support, or income tax for example. you should buy a title policy if you are concerned, I usually dont, because I know the Sheriffs Deed is as close to Virgin Title as possible (assuming you purchased a first position) I dont think you have anything to worry about. 

And while I have spent LOTS of time in Honolulu and Maui  ( my parents live on Maui for years) I get island bound everything is a 5 hour or more flight so that would not do it for me either.. 

@Brian OShea  Ask the daughter if her only source of income is $700 a month (is the baby's dad paying child support?)

They function in similar ways, but the main difference is that when you file the Series LLC you are incorporating the "parent" series, from which you can privately file as many "children" series for.

Due to parenting differences, we helped my sister and nephews find a house close-by, but now the residence is a bit big for our smaller crew and we plan to find another house to move into soon.
