Mike, I will have to disagree with you any several points.
Apartment complexes often have larger expense ratios as compared with a duplex or 4-plex. The reason investors buy them is because they can buy on the cap rate factor (commercial) and not the comp value (residential) which is often priced higher. Sure you have administartion, accounting, etc. but those expenses are spread out over all the residential investments which makes them less per, assuming you buy more than one or two investments. Apartments are usually operated as a seperate entity and all the admin./accounting/etc. expenses are for that single complex.
Of course I do not know all the operating expenses as the original question did not list them. It is not my property, nor did I have the benefit of looking at the P&L. Of course sellers always lie or mis represent OE and income so there is a need to estimate some items. The items I mentioned to get exact figures on are set things like insurance, taxes, etc.
There are of course averages nationwide, and sometimes, these figures are needed to get a valuation.
Any building with 4 or less units is residential, not commercial. When is the last time you got a commercial loan on a duplex?
As a full time landlord, you pay no taxes so depreciation is not an issue!?
What kind of BS is that. Perhaps the IRS would like to be introduced to you to examine your tax evasion scheme. If you make income, then you need deductions to offset that income inorder to reduce the taxes. For a full time "investor", I would hope you make enough money to be in the position to have to pay some tax.
Principle paydown is also relevant because you receive it when the property is sold or refinanced. It is not simple lost just because you cant "eat with it" today. It remains a return on the original investment.
You have promoted yourself as a full time investor and landlord here numerous times. From reading some of your blogs, you appear to be a painter, handyman, property manager, and book keeper just to name a few. As an investor, I find my time is more valuable networking, analizing deals, negotiating them, and managing my business. You also seem to have a niche in the older sfr properties valued under 100k and enjoy managing them yourself and dealing with all the headaches as well as having a high vacancy rate (according to your blog posts). If that is what you like, more power to you. It is just not for me and may not be for others. Investing in older sfr properties with lower income tenants, I can see why you would easily have the 50% OE. I prefer new multi-family units with lower maintenance and leave the headaches up to my property managers to deal with.
In closing, let me say that I did not intend to bash your business here, only to respond to your attacks on my statements previously. Perhaps we can agree to disagree on computing NOI and the differnce between res vs. commercial calculations. I do wish you success in your business as I would any investor. (by the way, the IRS comment was in jest)
Happy investing to all.
