The 50 percent rule in estate is really important. If you ignore it you will lose a lot of money. I know this because I have seen it happen to my friends. They thought they had a deal but they did not think about all the hidden costs. The 50 percent rule in estate helps you remember to include all these costs in your budget.
I want to tell you about my rental property. I bought a house for 200,000 dollars. The rent was 1,800 dollars per month. My mortgage was 1,000 dollars. I thought I would make 800 dollars every month. I did not know about the 50 percent rule in real estate. After six months the furnace broke. That cost me 3,500 dollars. Then the tenant moved out. The house was empty for two months. That cost me 3,600 dollars in rent. The property taxes also went up by 600 dollars per year.
By the end of the year I had made almost no profit. If I had used the 50 percent rule in estate I would have known to expect 900 dollars in expenses. This would have left me with 900 dollars for my mortgage and profit. My mortgage was 1,000 dollars so I would have lost money every month.
Vacancy is a problem for investors.
Many people think that their property will always be rented.. The average rental property in Canada is empty 5 to 10 percent of the time. This means that for every 12 months you might only get 11 months of rent. The 50 percent rule in estate includes vacancy in the expenses. If you ignore vacancy you are planning for your property always to be rented.. This never happens. I have seen investors buy a property. Then the tenant leaves. They cannot pay their mortgage for two months. They go into debt. Sell the property quickly. Do not let this happen to you. Use the 50 percent rule in estate.
Maintenance and repairs can add up quickly.
You might be able to fix things yourself. Big repairs will happen to everyone. A new roof can cost 10,000 to 20,000 dollars. A new heating and cooling system can cost 5,000 to 8,000 dollars. A new hot water tank can cost 1,500 dollars. Over ten years these costs can be 5 to 10 percent of your rent. The 50 percent rule in estate includes these costs. If you ignore them you will be surprised when you have to pay for a roof. I think it is an idea to have a separate bank account for repairs. Every month put 10 percent of the rent into this account.
Managing a property takes time and money.
You might think that you can manage the property yourself and save money.. Your time is worth money. Every time you get a call about a problem every hour you spend finding a tenant, every trip to the property these all take time. The 50 percent rule in estate assumes that you will hire a professional manager. If you manage the property yourself you can lower your expenses to 40 or 45 percent. Do not think that your time is free. I used to manage three properties myself. I spent 15 hours per week on landlord tasks. This time could have been spent on my business or with my family. Now I pay a property manager.
Use the 50 percent rule in real estate.
I want to tell you about a property I looked recently. It was a triplex in a sized city. The rent was 3,600 dollars per month. The asking price was 450,000 dollars. The seller gave me a list of expenses. It only included taxes, insurance and water. It did not include maintenance, vacancy or big repairs. The 50 percent rule in estate said that the expenses would be 1,800 dollars. The mortgage would be 1,700 dollars. This would have left 100 dollars per month for profit.
If the property was empty for one month or if I had to pay for a repair I would have lost money. I did not buy the property. Six months later the new owner had to pay a 6,000 dollar assessment. The 50 percent rule in estate would have helped them avoid this problem.
New investors are the most at risk.
They are optimistic. Want to believe in a deal. They find a property that seems to make money. They ignore the 50 percent rule in real estate. They think that their property is different that their tenants are better or that their market is growing.. Then reality sets in. I have worked with new investors. The ones who succeed are the ones who use the 50 percent rule in estate from the start. The ones who fail are the ones who think they are smarter than everyone. Do not be that person. Use the 50 percent rule in estate. It will not make you rich quickly. It will help you avoid losing money.
How to Build a Safety Buffer Beyond the 50% Rule
Once you understand the 50 percent rule in estate you can take it further. I think it is an idea to add a 10 percent buffer on top of the 50 percent. So of 50 percent for expenses you would budget 60 percent. This extra buffer can help you cover costs, like a big increase in insurance or a longer than usual vacancy. If you can still make money with 60 percent expenses you have a safe deal. If you only break with 50 percent expenses you are one small problem away from losing money. The 50 percent rule in estate is just the start. Build in some margin and you will sleep better at night.
Conclusion
Ignoring the 50 percent rule in estate can cost you a lot of money. You now know the cost of skipping this simple guideline. Use it on every deal before you make an offer. Respect the 50 percent rule in estate as your first line of defense, against bad investments. I have learned this lesson the way so you do not have to.
