It was mostly due to my day job income and low cost of living over a long period of time; however, real estate accounts for about 50% of our income through a small portfolio of short, mid, and long term rentals. 

I rent to one couple or small family for the full rental period - no less than 2 months and no more than 3 months.

.- Over a 10 year period cashflow will increase as rents increase (rents typically rise faster than property taxes, insurance, etc.)- The property should be appreciating, if purchased in a good location, increasing the owner's equity/wealth.- Rents will be paying the mortgage off, increasing the owner's equity/wealth.- If you hold a rental until death, you can pass it on with a stepped-up cost basis, limiting captial gains if then sold (limited by inheritance tax limitations).Too many newbies on this site trying to replace their day job income via "passive" real estate investing w/o digging deep enough to understand how it really works.

My draw down period is ten years of interest only payments then twenty years principal plus interest after that. 

Although the study may increase the gain, the gain may be taxed at a much lower rate making it a beneficial investment.If a property is purchased with the intention to flip or own for a short period of time (less than 3 years), a cost segregation study may not be significant.Overall, as long as you intend to hold the investment property for greater than a year, the benefits of a cost segregation study should be considered.

Keep in mind that they can increase that period if they get complains from the community, so make sure you're in good relationship with your neighbors.

For the 10 year period spanning December 2014-2024, single-family prices in Austin nearly doubled, yielding an annualized appreciation rate of ~9.4% in that period.With inflation close to its 2% target and an uptick in the labor market, The Federal Reserve may be taking a break from rate cuts.

How do you think the 2 relatives will feel about having their rent raised or being required to pay rent period?

The other thing to note is that the IRS only lets you have a 401K loan balance of up to $50K over a 365 day period. 

I've seen many landlords that get lucky with good renters for a long period of time, then everything falls apart when they have to deal with real difficulty.I looked up your property on Google Maps, and the street view looks bad.
