Investing on income producing properties is all about the “net operating income or NOI” that the property produces. Taxes, insurance, utilities, management, and maintenance are the usual components that are deducted from the rental income in order to get to the NOI.
The following are some thoughts about it:
1- Normally, you do not make the calculations based on 100% occupancy {even if you currently have 100% occupancy}. The best is to use market vacancy rates, the second best is using a 5% vacancy.
2- You might want to take a look at the spreadsheet that I have at
http://www.loanuniverse.com/sensitivity.html to kind of guide you as to how the NOI and the debt service is calculated.
3- I would not place any reserves aside, but just make sure that a portion of your assets is liquid enough so that you can pay the mortgage if a couple of tenants move out at once.
4- I have seen investors hold commercial properties in both types of entities {LLCs and Corporations}. I do not see any advantages in using either as you can elect to be a subchapter S corporation and get the same pass-through tax advantage. I think there are some benefits to the way earnings can be distributed among the members in an LLC, but this is going to be a one-member entity so I don’t see any. Nevertheless, I am not an attorney or accountant so consult one.
5- Do not buy income property on potential as you will be speculating other than investing. Someone mentioned here that they were thinking of buying a property but could not get a loan for it because it was appraising way lower than purchase price. This individual also mentioned that he intended to hold the property for at least ten years hoping for an increase in value. In other words, the buyer was willing to put up with returns that are lower than market for ten years for something that may or may not happen.
6- Strong financial standing, good credit, and enough money give you the opportunity to shop around. Commercial lenders normally do not ask for any money to begin their due diligence and only ask for money in exchange for a written commitment. This means that you can shop around with several until you get a good deal.
Good luck.
