I believe the interest rate is a bit higher than your normal mortgage.

Once you learn more about all these different ways then choose the best one that you believe will be the best fit for you that fits your lifestyle and will help you accomplish your goals.

the tenant. arbitrage would be someone having a long term rental agreement (usually at least a year) and a landlord isnt normally going to be paying the utilities in those cases

It creates a lot of friction with other tenants and normally creates a poor work life balance for the manager.

from an insurance standpoint it would probably dramatically raise your insurance costs as treehouses are normally looked at as a huge liability for injury.  

A lot of other markets 20 years from now could be ghost towns with little demand.But on the flipside, that safety/security comes with lessor immediate returns, as is a normal balance with investments (more risk traditionally equals more short term gain potential). 

Financial freedom goes beyond simply replacing your current income—it's about sustaining your lifestyle for life.

Perhaps someone with more intimate knowledge of the area can validate or dispel the type of neighborhood this is but it’s normally not good if that’s one of the first things to populate on the internet.

I agree with @Brandon Rizzo I think the supply will normalize as the migration to Texas has not slowed down and as builders make correction to a more balanced supply and demand (along with interest rate improvement) housing market will be better.

But I have a very low opinion of guru types (high priced, lots of upselling, big promises, selling a life style in their ads more than information, etc.)
