@Skip Gilliam I sense a potentially dangerous combination of circumstances: you have quite a bit of accessible funds, a lot of motivation to get into RE, but not very much lexperience. Ironically having money when you start out in RE is certainly helpful, but also a little bit dangerous, because it allows you to overpay. I have seen many people do that and to some extend it happened to me as well. Having money to invest allows you to use money to overcome obstacles. Money fixes almost everything in real estate. It fixes a bad deal, a leaking roof and foundation repairs you did not really account for, it fixes bad tenants and it allows you to out-spend your competition in a compatitive market instead of outsmarting them. It is very tempting when you start out to use money to compensate for skills you still have to aquire.
One of the golden rules is: you make money when you buy. When you look at the different ways of how you can make money in real estate (basically collecting rent, rehabbing, selling) non of them come close to the potential of buying right. To put this in perspective on an average single family you can make maybe $4000 annually in rent, you can invest 30k to fix it up and maybe increase the value by 40k (if you know what you are doing, typically renovations have a slightly negative return on investment). If you stage the property right maybe you can get $3000 more than fair market value. Those are all relativley small numbers compared to buying a property at a 25% discount - $25.000 in equity on a $100.000 property.
My first property was a duplex and I thought I was getting a good deal, because it was a short sale. When I look at the numbers today I would say I paid almost full retail (so I missed out on 25% equity). Despite the fact that my planning for renovations did not go much further than making it rent ready for the first tenants (in the meantime I have replaced the entire plumbing system and redid all bathrooms in the house, kitchens will be at the end of their life soon) It has still proven to be a solid investment in terms of cash flow. The one thing that I did right was to buy in a solid neighborhood.
If you expect to make 90k a year in RE I would probably expect a little more than 2 years. Most small multi family investors will tell you they make about $200 monthly a door after expenses and reserves. So you will need about 38 doors to reach your goal. If you want to do this in two years you would have to buy a puplex about every 5 weeks. Typically your growth curve will look much like a hockey stick. You will buy one or two properties in the first year and then maybe double the amount in every following year.
Hope this helps a little bit with your planning. It can be done, but it will take quite a bit of work and dedication. Good luck and let me know if you have any questions.
