Can i fix the bad home to make the Feng shui better?

I plan to purchase a home, location is ok, but feng shui is bad, is feng shui real and should i not buy a home because of it? If feng shui is bad on the home like where the door is fixing and such, can i fix the home to make the feng shui better?
how did you know that the house has a bad fengshui, if you don't know fengshui? i am just curious. because if you know what is wrong with it, then you must know how to correct it.fengshui does not only deal with the inside/ contents of the house, but the most important aspect that most people fail to consider is the location of the house - does it have good fengshui; because chi travels on the roads outside the house. these roads deliver chi to your house. chi can be good, it can also be bad.regarding fengshui solutions, it really depends on the fengshui concept that you are using. like in flying stars, you can have a major (at least 2/3's of house) renovation and replace or repaint the roof to change the period of the house, thereby changing the flying star chart of the house. but you need to know what you doing. fengshui, is not based on guessing or trial and error. but the concepts are used by fengshui masters/ practitioners to measure, calculate and analyze situations regarding your house.most people will say that a slanted door might be bad, but if it was tilted for a reason - in fengshui, this can be good, depends on the concept you are using.
I am all for Feng Shui and anything else that is good for me and not harmfull. I also know that you can add furniture and make adjustments to change the feng shui of your home however there are things you cant change such as a home in a dead end means you will fail if you open a business and a home located at the end of an intersection is very bad and unchangeable. Its very complicated as a house facing South is lucky but if you can see the fireplace or back door from your front door is unlucky. No way to achieve perfect Feng Shui unless you purchase the perfect land and build it yourself! Good Luck!
Feng Shui is about creating an environment that will support your health, wealth, relationships, and, happiness. Think about it, if you are in a space that you are comfortable in and feel energize in, you will be more productive and healthier in both your mental and physcial well being.
It has been proven time and time again that we are creatures of our environment. For example, let say it is a beatiful day with blue skies and sunshine outside. If this were the case, you would want to be outside and enjoy the day. You would feel more energize and in a good mood. However, if its cloudy, drizzling, and cold, you wouldn't want to be outside and your mood changes. That is why Feng Shui is important, because it looks at your environment and aims to create a space that makes you feel more energize and productive. This in turn leads to better health, stronger relationships, and improve finances. Every aspects of our lives are linked. Even if you have lots of money and your health is terrible, that is not happiness. Or vice versa, if you are in great health, but you are so stress because you are living pay check to pay check, that is not happiness either. Feng Shui's aim is to balance all aspects of our lives by creating an environment that has good chi or energy.
To answer your question, you need to consider how much work you have to put in to fix the Feng Shui of the home. If it is just minor and easily fixable and the house is in a good location, then go for it. However, if the home requires major rennvoation and can be costly to fix, it is advised to look for another property. It is better to start off with a good home in a good location with good Feng Shui. However, keep in mind there is no such thing as perfect Feng Shui. Every property needs some adjustment, it is a matter of how extensive the adjustments are and how costly.

Depending on how many modifications are needed to fix the issues. If they cost to much, it may not be worthwhile.

The aspects to chose a new house is,
1. The location of the house
2. The right time and the right direction to move in the house
3. The house's layout, exterior, interior and etc
Feng Shui is so deep and detailed to determine if the house is good or bad. It's impossible to tell you what to do over the Internet.
