In addition to how much, you can also choose when in the investment lifecycle to apply leverage.

You have to work the numbers backwards to plan on a replacement at an appropriate point in the life cycle- before maintenance costs rise dramatically, and a slow failure causes more damage to surrounding elements.If the structure is new, or significantly rehabbed, you need to determine/estimate the design (or useful) life of each major element.

The main reason I am drawn to new at this point is the low likelihood of needing ANY maintenance in the first 5 years; since you got it new, you are in charge of how well maintained it is over its life cycle, and have control to sell at the optimum time so that you can re-invest that money into another new tub in need of no maintenance. 

It's a long customer life cycle.

Our model and services have changed significantly.We now provide services throughout the entire lifecycle of the investment, not just the initial due diligence.

I try not hover on these threads because I feel like having a lot of input from a Spartan shill like me sort of defeats the purpose, but I also don’t want to keep missing questions from people when BPs tagging mechanism fails.All the best,Clayton Better late than never ...You understand the limitations of your using actuals for only the first 10 years of the lifecycle but I am unsure that all readers have this understanding.Virtually all components on a house have a lifespan greater than 10 years.

By failing to have an adequate Reserve Funding Plan to cover these expenses so early in the life cycle of a property is a major Red Flag.

Thanks for the perspective on Quickbooks desktop vs. online, @Daniel LeeAlthough I've gotten "used" to Quickbooks, I wouldn't say I love it by any means and I'm in the middle of "forced upgrade" in the lifecycle of my software.

Historically speaking, the average life cycle of a loan meaning you either refinance, sell or buy a new home in that time period, means that if there is a possibility you are not there in 7-10 years than an ARM makes sense.
