@Andrey Y.
Definitely valid questions. With real estate investing it all boils down to the math so if you're not satisfied with the projected returns then it would definitely be too much of a hassle with all of the headache of purchasing a home. I asked myself the exact question 6 months before i took the plunge into turnkey. I like that @Jay Hinrichs pointed out the steady nature of note investing. My person REI journey started with the intent of doing note investing exclusively because of the hassle free nature.
I did find a note that i was able to purchase a fraction of ($17,000) that pays 10% for 12 years. Truly mailbox money, and no downpayment. In fact i don't even have to pay the note servicing fee. The only expense for this investment was the $15 to wire the money to the broker. After this deal, that is still faithfully paying, i remember looking at some turnkey deals and really turning my nose up at them thinking the exact same thing "why would anybody to this for $150 a month" here is why i have changed my strategy to a turnkey that may pay 10% ROI versus a virtually no hassle note investment
Downside of notes:
-Vacancy on Money. With an amortized note you are getting back some of the principle every month. This means less and less of your money is deployed capital until after x years it is all gone. This really hurts if you don't have enough notes in the pot to grow quick enough to re-deploy capital. With a rental your capital is always deployed, and it won't disappear in x years.
-Taxes. Again a simple math equation. interest income is taxed as regular income while a rental property is wildly taxed advantaged.
-Availability. I think a good note needs to be on a property that is good enough collateral that you can comfortably foreclose upon if needs be. This is tough if i only want to put about 20k into each deal as i don't want a note collateral to be a 20k property. This is solved with buying a fraction of a note, but i have learned that they are not as easy to come by. @Jay Hinrichs if you have any suggestions on where to get fractional notes for smaller investors my ears are open.
-No Upside potential. Notes are not going to have the potential to appreciate, or get equity pay down, which are icing on my projected returns. Notes have limited ability to produce anything other than the interest rate.
So where i don't mean this to be a post on note investing, maybe this helps answer the question of why go through all the hassle of a turnkey property for relatively low cash flow. I also look at the ROTI, or return on time invested. With a good turnkey company I am not having to really put too much effort into the investment. So for something that all i have to do is check my bank account once a month, ill take the $150 all day long.
I think there are some better returns out there if you are willing to not go turnkey, and sacrifice the time that may need to put in.
