In my spare time I'm a buy and hold SF/MF investor here in San Antonio.

To keep it brief, I'll provide the high points (and spare everyone my analysis paralysis scribbles).I've been working on a deal for a buy and hold (two duplexes) that yield a gross rental income of $2400 / month.

Then had a contractor with a bobcat dig a spot and compact the gravel.

Well in the post above you mention being a little low on capital, and in a rehab you always want capital to spare cause there is very frequently unexpected costs.

If you have cash to spare then they may be...just figure out your "what".

My goal is to build up enough of an income stream so I can quit my day job and spent more time with my kids.While I don't have much spare time at the moment I do have some funds available and have started to dip my toes into some low effort deals.

I mean I know the gameplan needs to be established but at the same time you need to know how to protect yourself and the time you have spared making a deal if buyer wants to jump.

Sinking concrete is usually a sign that your base material was not sufficient, or not compacted adequately or the wrong type of material. 

Another good thing about doing our basement is that we could do it in our spare time.

I rented out the spare rooms to help with the mortgage.Be sure to check out The BiggerPockets Ultimate Beginner's Guide
