Unfortunately, there are no properties that would fit the 50% rule but there is plenty of money being made. Don't get me wrong, I keep the 50% rule in mind because there is a lot of validity to it but I do my best to find way to mitigate that 50% ie managing the property myself, negotiating deals with contractors, plumbers, and electricians, and perhaps purchasing property that has had the critical and expensive parts updated recently. I basically add what needs to be done in the next 5 years to the PITI to see where Im going to be.
I also have a combination of 15 and 30 year mortgages to balance the cash flow vs. principal pay down. In other words, if I have a property with plenty of equity and a very low 30 yr payment which has tremendous cash flow, I feel like it almost helps balance out the next property if the cash flow is a little tighter but its on a 15 year mortgage.
The catch is that there is literally 0 vacancy and no forclosures in my market so I don't know if anybody will be able to relate to my situation but I have actually found that this is a fairly good market to get started in because while Im not swimming in money, I know I have good renters every month which keeps things very consistent.
I realize Im cutting it a little close but the surplus of renters has enabled me to get into a number of different homes by releveraging the equity from the properties that are on a 15 year mortgages and it has actually worked out fairly well and could now bank roll just about any major occurance. Fingers crossed.
