My wife and I have lived in our condo for 17 months. We are moving across the country for a new job, and are converting the condo to a rental.  We don't intend to ever move back into it.
From a tax advantage and over...

Ask yourself where you want to financially in 10-30 yrs.

Also I do have income I’ve been on my job for approximately 2 yrs now

I have lived in this city for 30+ yrs and watch this city grow and grow and grow non stop..... 

First time poster here, been lurking for a long time now.Little background: I am 25 yrs old and currently live in Austin, TX.

Firstly hello - long time reader and first time poster Some advice neededI have 155k (24 yrs) left on Primary mortgage at 4.1% (home worth 320-350k)If I cash out refi I potentially can take up to 100k out / drop interest rate to high 2's/vry low 3's and have a payment $200 up on my current monthlyI will make around 160-200k USD this year from my jobs (more if I buy a rental) and my mortgage is within $100 a month paid off by roommates (I cover the utilities which are $300USD a month)Question is with money being really cheap would it make sense to cash out 100k to have it and either stick it in the s&P500 or use it for DP on 2 or 3 investment properties?

At 17 yrs old you don't really have any expenses so take advantage of it and work as much as possible and save up all that money and buy duplex low money down and house hack it live on one side and rent the other.

Parents passed yrs back leaving 2-4 rentals and an apt complex to the kids.

I just googled "side gig" and theres a few pages of reading.Yes they are all fairly manual, driving your car etc.Having been in the investing side for 10 yrs now I actually don't know side gigs IN real estate.   

I am 55 yrs old and my advice to you would be to chunk in all your expenses with cash flowing RE like I did and am now financially free.
