In the last few months many lenders have made it increasingly difficult for new entrants to break into the buy to let market. The credit crunch has hit lenders hard and in response they have hit the buy to let investor harder.

At the moment banks, don't trust each other and because of this they are currently no longer lending freely to one another; this is having a knock on affect on their lending to the general public and investors.

The number of mortgage products available has decreased by almost 75% since April 2007. Significant players like mortgage express have pulled key products leaving many buy to let landlords wondering how to make their next property purchase stack up.

Every Tom, Dick and Harry seems to be claiming that they can be the solution to the property investor's financial problems and that they can still offer products like instant remortgaging. Many professional property investors are staying clear of the majority of these deals because they are concerned that many might not be legal.

Is it a good idea to be buying property at the moment?

The answer to that depends on what you goals and strategies are. Are you a buy to let investor who is in this for the long run? Can you handle the negative comments in the media and not have a heart attack every time you hear the words "Property Market Crash"? If you answered yes to both these questions, then you should still be buying.

However, you should be analysing your strategy, as it might need tweaking in the current market conditions. By following the guidelines below you stand more of a chance of building a robust portfolio at this time.

- Focus on buying for more than 25% below market value.

- Focus on buying lower value properties with good rental yields and positive cash flow.

Stay away from anything that might prove difficult to get comparison for, this includes off plan developments.

- If you release equity from your portfolio, don't put it all straight back into you next property purchase. Try to build up a rainy day cash reserve, just in case things get any worse.

- Never, default on a mortgage payment. At the moment if you miss a mortgage payment on any of your properties, you are probably going to decrease your financial options even further. Lenders are being more stringent with applicants than they used to be and the odd blemish on your credit file that you might have been able to get away with before may now stop some of your mortgage applications in their tracks.

- You, have to be looking at maximising your return. Look for properties that you can easily rearrange the internal structure. Doing things such as moving internal walls around to create added value such as an additional bedroom, could be crucial at the moment. Do everything you can to entice the buyer.

- Consider advertising that you will pay stamp duty and all legal fees, this can be the difference between success and failure in the current market place.

For the investors that understand the property and financial markets and learn how to work with them in any and all conditions, the next few years promise to be times of learning and expansion, not contraction. Yes there are difficult times ahead, but out of huge challenges can come tremendous growth.

If you seem to have hit a road block, use every means in your power to push through it. Maybe you need to learn a new skill such as lease options, sale and rent backs or investing abroad. Be adaptable, be resourceful, ask questions, learn from others, do joint ventures, make up your mind to push forward not go backwards.

This is when the men get separated from the boys, the novice investors from the professionals and tomorrow's property multimillionaires from the "I could have been somebody" crowd.
