well first let me say that with 585k to invest, you are in a totally different league than me and my partners. that's big money. so i would never even attempt to give you advise. i mean, the advise i gave was just simple logic. but then again, when it comes to business and investing, no matter how big or small, it all boils down to good ole common sense...at a basic level.
having said that, i would be interested in hearing about your "mistakes". have you ever written them down and looked at them? i know you have them in your head and maybe even on some painful financial paperwork, but i think writing them down helps. [i'm a counselor in my day job :D ]
writing them down with specifics would help you to match them to future decisions. writing down the numbers, the contacts, the areas, the businesses etc. can possibly steer your investment strategies in the right direction.
are you involved with any partners in your real estate ventures?
who manages your apartment complex?
who will manage your future apt complex?
and again, i'm not versed in the commercial arena(...yet), nor do i deal with the amount of cash you are, but we all know that every type of investment comes with varying levels of risk. but i mean, if a local economy goes to the toilet - it can still effect your apt complex. issues like migrating demographic groups can impact negatively on your apt complex as well right?
i mentioned the strip malls because a friend of mine invests in them and he says they're the best kind of rei. with long-term triple-net leases and solid businesses, they can be very hands-off as far as managing, whereas an apt complex is just that....more complex.
the reason i'm saying this is because, if you're dealing with over 500k in investment funds, i'd presume that you or the people you're working with KNOW THEIR STUFF. so i mean, investing in excellent triple-net leases would be a sound investment strategy because you're dealing with people who know what's good and not good, thus it's very safe, whereas for someone like me (who doesn't know a lot and doesn't have the resources to analyze major purchases) such an investment would be very risky.
please, tell me if i'm dead wrong. again, i do NOT want to come across as if i "know what i'm talking about". cuz when it comes high-end commercial rei, quite frankly, i don't.
but getting to my point, what were you're investment mistakes?
