I've been lurking around BP, soaking up everything from books to podcasts for a few months.

Great time to start soaking it all up, wish I started at 21!

I'm new to the area and the field so I'm just trying to soak up as much information as possible at the moment.

For now, I am just trying to be a sponge and soak up all the information I can get.

I raised the lowered ceiling, leveled the sloping floor, added under the floor heating, a soaking tub and separate shower as well as high quality quartz tiling and glass shower with brass fixtures and double sink.

I'm pretty sure BP has an article about realtors working with investors that is definitely a good thing to read up on. other than that be ready to spend a little money, be ready to run comps, and re-hab "numbers"  on properties for your investment side all around just prepare yourself and soak up as much information as you possibly can because learning the realtor side of the real estate world and the investment side are two, I wouldn't say completely different things but there is a lot more information to stack on top of the realtor knowledge.

I'd go with stained or polished cement With stained they can usually add and 1/8th" or so overlay (they then stain the overlay) so any preexisting stains or anything is fine Polished cement (in my experience) is the opposite - they essentially remove 1/16-1/8" of existing cement, so surface stains will be removed but anything that has really soaked through may still remain to an extent Yes water will get trapped between the LVP and existing cement/water barrier - for this reason I would not do LVP Could go tile - but why would you when you can stain/polish it for cheaper and not worry about cracked tiles years from now when you can't get a replacement 

I am soaking all the knowledge and wisdom from BP books about real estate.

I've been an active member of this community, soaking up knowledge, sharing my experiences, and networking with many of you.

Just soaking in the info.
