Can you pitch a target market as a standard of practice?

Here is a 3-2 that I did a practice analysis on to see.

I’ve been analyzing and practicing how to figure things out.

I relocated to Houston Texas and paid cash for my home.

Hopefully completely relocated to wherever I invest!

Is it best practice to always invest in all real estate properties under an LLC?

Or is common practice to make an offer then find a buyer?

I've seen this relaxed to 2.5X depending on location and the price of your unit. if rent is 4k a month then 2.5% is 10k a month gross that gives them 6k a month before tax to live on.. if rent is 700 a month I think it needs to go the other way  4X  that gives them 2100 a month to live on as opposed to 3X were they are living on maybe 1k a month that's a pretty precarious situation for many one flat tire and rent gets missed :)  I am not saying you are wrong in the intent to make sure there is enough living money, but in practice I have found that my cheaper units (class C) have the tenants paying a higher percentage of their income to rent and they simply live on not much money.My B class properties can get tenants easily at 3X the monthly rent (start at ~$2.5K (3 BR) and go up to ~$4K (3 BR)). 

I think you could take practically any industry and play out a scenario in which this will have a major effect on that industry and it's employees. 

I feel they are over reaching and out of step with modern STR practices.
