My current goal is to start with house hacking and move on to long-term single-family rentals.

My (non lawyer) read of the SC rules paints a much different picture in those jurisdictions than what you discuss in TX - where it sounds like you own effectively nothing but a tax note until the close of the redemption period - you can't take possession and rent the property, real estate taxes during the period are still the responsibility of the original owner, etc.The below is from the County of Charleston SC's website regarding the tax sale and how they work in that particular jurisdiction - certainly not the authoritative source of their state statutes, but for posting on a forum, I'll take it for now. 

My wife and I did a lot of research, attended live sessions, and I connected with some current and former students and got positive feedback.

Hello everyone, I am currently a senior in college (graduating in May) with a goal to purchase a duplex this upcoming Summer.

I haven't seen anything below $3,000 in Texas for RC in a couple years unless the home is brand new. 

I currently live in a 1,000 sq ft home on a 7,000 sq ft lot in San Diego county.

The best thing you can do is contact an real estate agent / broker who can run some comps and get you an accurate ARV range so you can forecast things more precisely and have a better idea of what these types of properties are actually worth and currently being sold for.

Do I need to provide SSN for a mortgage estimate.Thanks For a mortgage estimate, you do not need to provide an SSN. 3rd party broker is always the best since many direct lenders have different guidelines.

I have one currently and it is very successful.
