Does it harm your credit if you do more then one loan pre approval at the same time?

A tort is a civil wrong that causes physical or financial harm to another.

Even if it was in violation of the lease for the tenant to change the locks, if I get the keys, no harm/no foul in my view.If I am not getting the keys, that probably means the keys are the least of my worries - legally or condition-wise.Exception: if I weren't already evicting (or the tenant wasn't already vacating), and if the lease wasn't near the end, and if the tenant was troublesome but paid on time, then I *might* use the change of locks as an excuse to terminate the lease (if the lease allowed me to do so) and then serve the tenant with a 30-day notice.  

Reacting to bad tenants, threats, or fear, will cause you more harm then if you sit back,  implement your lease agreement (according to the laws of your state), and let the courts do their job. 

Full disclosure: I am a newbie with no entities of my own.Per the podcasts I've heard related to entities, there is no harm in flipping a few in your name, before worrying about asset protection.

In the end, this means you are not actually "spending " you money...you are "using" your money, as many times as you want/can.Second, the success of this strategy as @Brent Coombs has touched on, is very much Market based (as in dependant on the RE Market you are investing in) since it involves getting properties at a discount.Third, it works best when you are using all cash, or a cash-like substance.  

If they are being considerate and giving adequate time for the old landlord to find a new tenant no harm no foul.

I knew I was gambling when I mentioned money but I've seen plenty of posts asking for advice and only receiving welcoming messages with no substance so I wanted to get some response, even if it was just fishing. 

There is mold and mildew and different types of strains so more harmful than others.

Question should be, how is the seller harmed, did he lose marketing time toward the end of the summer and/or a sale?
