Here are some important facts with respect to borrowing against the 401k: 1) It must be a 401k, once you rollover your funds to an IRA, you don't have that capability. 2) You can only borrow up to 50% not to exceed $50,000. 3) You must make at least quarterly payments, with an interest rate set usually at prime + 1%.

Costs went up and revenues dipped or were stagnant due to increased supply. 

 @Chris SeveneyThe long-shot play I became aware of; Capital Improvement Project Funding that the city/county have allocated for projects that meet 2 criteria.Have a lifetime greater than 10 yearsCost more than $50,000I believe, even if the water and refuse collection run is only 1000 ft, that may not qualify but to do it "right", that two mile run would allow the entire subdivision to be supplied with services.

The market determines price based on supply/demand and if you think there's not enough supply - then go ahead and increase the price. 

Cleaning and supply fees have stayed about the same for me. 

Eventually when the property sells, you will have long-term UBIT, which is about 20%, and remember the carry forward loss capability.

Some would consider warehouses to be the backbone of today’s supply chain.

Personally, I generate steady cash flow through rental income from workforce housing and multifamily properties, but the value really comes from the appreciation that takes time but is happening, especially in markets like Dallas, where property values are rising steadily due to a major supply demand imbalance.

It doesn't require all the finesse that wholesaling does - you have the money, you buy the property - regardless of your personal capabilities.  

They haven't retreated enough to create an intrinsic asset and that's because supply has been an issue.You want to invest out of country, and I am assuming blindly?
