It goes back to what I refer to as one of the top 3 problems of many methods of analysis...way too much reliance on percentages, and not enough on the end results in actual dollars.As an investor, schools, nearby shops, freeways, mean nothing to me. 

This is one of my biggest issues with too many of the REI analysis formulas...they rely way too much on percentages instead of dollars...and can be very misleading. 

Even so, the bottom line on Schedule E will often be zero, because the rental income will often be fully offset by deductible expenses.Step 6: Write off the personal-use percentage of mortgage interest and property taxes as itemized deductions on Schedule A of Form 1040, subject to the new Tax Cuts and Jobs Act of 2017 (TCJA) limits for 2018-2025 (see “TCJA changes affecting vacation-home owners” below).You are allowed to carry over any disallowed allocable indirect expenses to future years when you can deduct them against rental profits (if you ever have any).Controversy regarding how to allocate mortgage interest and property taxes The IRS says you should use only actual days of personal and rental usage to allocate all non-direct vacation-home expenses, including mortgage interest and property taxes.

It's OK to utilize generic percentages when conducting initial analysis, but once you identify a property that may be worth pursuing, I always feel it's best to know how large of a furnace i'll need based on the square footage, what the current state of the plumbing and electrical are, does the home have large decks or long driveways that will eventually bear large expenses that you may not incur elsewhere. 

If you have other partners and don't want to affect the ownership percentages draft a note stating he terms and conditions of the loan to the LLC.

In a lot of leases, holdover tenancy will result in additional rent, sometimes at an increased percentage.

In your opinion, is an acceptable percentage of ground lease rent of the total gross revenue?
