Buy To Let Mortgages

If you have a mortgage to buy property that will automatically have to pay capital gains on profits?
I have a couple of properties buying for the mortgage and wondering if there is a way or a reduction in their taxes, you may have to pay when you sell or not, and they automatically know when the property is sold and Chase for money?
You must be a little careful here if you are caught for tax evasion, you can be jailed. Basically, if you live in the house for 6 months then you can get 3 years in tax relief for sale. If you sell after 4 years must pay tax on the 25% increase in the value you purchased when sold. If you have not lived, you have to pay tax any increase in property values, except for the house we live in You must also pay income tax to any rent, but you can compensate This compares with many things, including interest payments in martgage, cleaning, maintenance, etc.
