I don't really want to tread water, or worse go backwards.

Darryl Lin , I am an investor in the Hesperia market for about 3 years and got few SFR that I am renting, the high deserts is a growing area , although CoCr is around 5-6% but you are betting on future appreciation , LA and OC Market is over saturated with renters , many of them can’t afford rent anymore , so many are moving towards the east , 15 years from now , homes should value in the $500k ( my opinion ) think of it this way , a river with over flown water branching out of its track.

Water heaters, furnace, plumbing leaks, replacing a roof, replacing the main water line, tree trimming, microwave replacement, etc. $20-25K would be awesome but you can likely get by depending on condition for $10-15K. 

I would have to say that the curtain rod would be easier, but if you are worried about caulking and don't want to risk water damage then the glass doors might be worth the investment.

No matter what the current only bathroom needs remodeled asap due to water damage starting.. thoughts on navigating that with a current tenant?

I have to do that with the water bill at two of my rentals as the water company will only allow the owner to pay the bill.If it is a condition of the lease, you can also give them notice that they are in violation of the lease and start an eviction process. 

Olympic sized pool, hot tubs, on-site restaurant, yoga, pilates, gym, steam, sauna, and management company to take care of it all.

For example, a 5 million dollar investment into an MTN "pool" (for lack of a better descriptive word) will yield a return of 15 million in under 30 days?

If we can't then how can we provide extra things like dog bowls, water etc if we do not know?
