@Link McGinnis Great response and great points that you have brought up.
I could not agree more with the utilities. These should be on the tenant and they should revert back once the tenant vacates the home, this is especially useful when the winter months set in and the home is empty. A "landlord" or fire policy as most companies refer to the insurance on the home, is actually more expensive most times then traditional insurance. Even though you are not covering the contents inside the home, the insurance company takes into account that you are not living there and a tenant will not care for a home the way you personally would. A home that price I would budget $700 to be safe for insurance but calling and finding out in the research phase of the deal is excellent advice. Taxes also factor into the home and something you can check online so you know exactly what that expense is going to be every month. If paying PMI, you can always find a mortgage calculator and input your own figures to get an estimate for monthly payments after your escrow account. For maintenance and vacancies I always budget 10% of the income to make sure I have enough in reserve when needed. When it comes to a contract, make sure you cover all points. Link mentioned exterminators, for my lease I always make sure I inform the tenant they are responsible for pest control beyond termite treatment. I also make sure I add a clause about cleaning clogs and drains. If you don't have this in the paperwork you will be cleaning these more then you would think. Side note, if the home is on a septic system it is usually on the owner to pump this. Garbage service, once again, I require the tenant to pay this and make it mandatory, you don't want to pull up to a home and see the back porch filled with trash due to cheap tenants. When managing the home yourself you have to remember the home is your business. When you give someone a chance it will more then likely come back to bite you in the wallet. Screen your tenants and don't rent to friends or family. Be strict on the rules and regs of the lease as well as the payments. An inch quickly turns into a mile in this business. Last but not least, never trust zillow. This and bad contractors have led more up and coming investors down the money pit and out of the business. You make your money when you buy the home. Look at the sold numbers in the area in the last 6 months for similar homes to the one you are looking at, don't just use the zillow estimate. Some times you can also determine rental prices based off the homes that rented in the area. Tax value of a home also does not mean repair value. Great job on doing your research, build your skills but don't get stuck always looking at deals and not end up doing one.
I am in the area if I can help with anything. Good luck.
