Will interest rates go up or down when Freddie/Fanny are 100% privatized?   

I would keep it in a high interest bank account might as well earn as much gain as you can no matter how small it is.However I think some debt pay down would be great not to the point where you are not liquid enough to Jump at another opportunity or can’t make a major repair when it arise.

And is what I wrote down below right or not?

I'm a bit of a nomad who doesn't like to put roots down too deep ;)  

It could cause a low spot where things slow down and then it all compounds until there is a clog.

I would guess less than 1% of deals are seller financed - and most of those are still done with 20% down.

When I inquired about it, plumber said lining, it is usually not prefect since this is PVC breakage not just pipe cracks and the cost saving is not significant enough and maybe headache down the road.I will try to get more quotes and maybe a company that specializes in pipe lining options.I was told foundation work / under slab pipe repair is common in the Dallas TX area due to soil type.

I would have knocked that sucker down with her first tantrum.  

I do not have to much cash for a down payment but was thinking of doing a HELOC on one of the rentals to get more cash and go the BRRRR method.

If it discharges 5 foot from the building and there is a low spot running back to the building, then it is going down hill back to the building.
