Merits of buying apartment houses and renting them
I am not going to argue the merits of investing in real estate (I am a fan I think it is a great idea when done right).  I will assume you have done your due diligence and your numbers are correct, so let's go through your questions point by point. What would be the type of taxes I should expect?  NONE. You are a real estate investor and the US government loves you. Everything is tax deductible and odds are your investment properties will actually manage to shelter some of your W2(day job) income and you will pay less taxes on that too.  Obviously I am exaggerating slightly find a CPA (certified public accountant) that is familiar with real estate, but here are a few examples. I am not a tax professional but hopefully this gives you an idea of what sort of tax benifits you can expect.   How is Insurance cost calculated?  Best advice I have call a few insurance firms and ask them.  You will need landlord insurance make sure you are covered if a tenant gets hurt or burns down your property. You can expect to pay 15%-20% more for landlord insurance than regular insurance (100$/month is not a bad number to just plug in when running numbers its probably high).  Also your lease should require tenants to have renters insurance to help protect you. Have a liability conversation with a lawyer and think about LLCs.   How is the house price increase going to act as another source of income?  Appreciation can be another source of income but it is not really that useful in your scenario.  It is not liquid you will not realize it until you sell the property and then you have to pay capital gains and depreciation recapture on it.  There are methods to get access to the gains on the property without paying taxes.  This is done by leveraging the property, you get the equity but it is not counted as capital gains since you have to pay it back a mortgage or home equity lines of credit (HELOC) are examples of this.  I am not recommending these just making sure you are aware of your options. Please let me know if I am calculating anything wrong but my projection for one year is about $8.4k per house (assuming no maintenance is needed) I would say you estimated profit is on the high side.  Not being involved in your market it will be a wild guess but I would expect you to realize cash-flow per house per year of closer to $7,000.  Maybe even lower given your inexperience.  Some Costs you need to remember to account for: Taxes, Insurance, Vacancy, Repairs, CapEx, Property Management, Utilities, Lawn Care, Snow Removal, HOA Fees. All-in-all expect 50% or your rental income to be spent on the property.  If you do well you can be pleasantly surprised.
