I have 2 mortgages, my wife has 1. So we can still buy several more, and hopefully we'll sell our current house, so we'll each have 1 mortgage.
The point of the RV comment (which I did not make clear b/c of my limited attention span) is the question, "does it make more sense to buy owner occupied or to live more cheaply in an RV and save more and buy properties as an investor?"
The advantage to owner occupying is obviously being able to buy with 3.5 a 5% down. My houses so far are roughly around $100,000 a piece. So $5000 versus $20,000 - $25,000. The advantage to buying as an investor, is no moving/decorating expenses. That always seems to cost a couple thousand. No working on things just for my family - for example, we have dogs so the fence has to be upgraded. With just a rental I wouldn't do anything with a fence as long as it wasn't a safety hazard, or an eyesore. Also, the rent $ we got would probably be higher than what we will spend living in an RV. Estimating here, but our current rent minus management fees are $700 and $800. And then add $150 for utilities. So let's say it will cost 900 to owner occupy per month.
In the RV it will be more like $500/ month, plus the cost of the RV. And I'm estimating around $20,000 for the RV.
So I am estimating that it will be cheaper to live in the RV, but definitely not $15000 cheaper. Maybe $5000 cheaper, mostly from savings on moving costs, fewer renovation costs, costs related to not buying new things every time we move. And at that point, if it is a difference of around $10,000 to buy it as an investor, mayb it is worth it? If we buy as occupants, there will be PMI, and a higher mortgage. But a lower interest rate...
Speaking of my dogs though, this question will be moot for a couple more years because of the dogs. 2 of them would be fine in an RV and an RV park, but my German Shepherd not so much. (Big, protective and a barker.). But, not to be morbid, that will change within the next 5-10 years.
