I am about 12 yrs older than you, and I have been doing both for last 4-5 yrs.

I only took out of my IRA the down payment ant about 30% more to pay for the stupid tax for investing in the IRA anyway and the regular taxes too, which we will pay no matter if we sell now or some imaginary date in the future.Last, let's say you were to achieve success and have 1 million in you retirement IRA when you retire, financial experts say, you can take 3.5% out each year and not out live you money by 88 yrs old.  

Here's the flex part: you can lock in for 5, 10, or 15 yrs, for 2.99, 5.5, 5.75%. 80%LTV, they do 90 but the rates are not nearly as good.

I know GA is different than CA but I was buying 2001 double wides on their own land off auction.com 2 yrs ago for $18k to $25k total, home and land included.  1998 to 2004's for that little.  

My degree is in Electrical Engineering with 5 yrs of work exp.

15 yrs is fine for Citrus you will get another 10 years of high productivity plus start the 15 year depreciation all over.

I have a few questions about this and roof repairs in general:Calling the roof "10 yrs old" feels dishonest to me, is simply layering over existing roofing enough to call the roof "new"? 

I might be biased because I went OOS with my money, but I feel that home values will drop more than I will be able to pay down the mortgage in next 10 yrs.

Given your change in income source, you will need to season it for 2 yrs to get a conventional loan.

I am looking to invest in detriot because the #s show me a market similar to the one we had here in ATL 4-5 yrs ago when I was buying properties for $40-50k each which I am am selling for $140k unrenovated & $230k renovated.
