This can cause a build-up of tension which get released (materials shift) suddenly making a knocking or cracking sound.  

But I muscled through the problems, and am kind of wishing I'd not stopped buying while I sorted through them because I was buying right!

I have a degenerative muscle disease that is slowly weakening my arms and legs so I'm hoping to retire in 15-20 years, and also have enough income to help my kids thru college.

I started with a mentor and just went out and do it, muscle memory.

Might ease the relationship tension but still allow you to make a nice profit.

And they have empty lots, so they essentially control the supply of homes and could flex their muscle to keep us from filling our lots.

Just like you can leverage the skills of a contractor or attorney to save you stress you can do the same with management.Of course, I always prefer just doing what you would do for any other tenant and telling him it isn't personal but it is a way to cause family tension and some people don't like that.Do what you need to do to sleep at night and keep your business a business!

Even if it's all in writing, tensions can get high when it's someones home.  

I love fishing, muscle cars, camping, and all wildlife recreational activities.

But then there are sometimes life-changing situations, that push us into a corner and we are forced to flex those abilities, like a muscle, in order to survive.
