I have done the calculation in excel with my terms and my normal cashflow and spending habits and it doesn’t work for me.

I support myself and travel the world by working online (teaching English and social media marketing). 

If there is a title insurer willing to issue owners coverage without exception to claims of unknown heirs or the use of a power of attorney (I highly doubt all your foreign sellers will travel to the US to dump this property), then things should be fine.That, however, does not eliminate the need to deal with FIRPTA.

Note: If you go to the same meeting each month, you can do detail tracking for a month, and can use same detail to estimate expense for rest of the year.( If nothing changed)2) Meals when traveling away from home - 50% is deductible unless the meal is provided to the general public (like Open houses) than it is 100% deductible.3) Expenses for Meeting with investor4) Expenses For Meeting with realtor5)Going to investors meetings.

It starts slowing for months and the early warning sign is increased inventory (non seasonal), then prices travel down over months or years.

Your job is to keep the property safe and habitable, not to mediate disputes between neighbors. 

Do investors travel to these properties to view them before making an offer, or at some point after an accepted offer (during inspection s)?

So you can deduct the cost of the travel while catching up with a friend or family member.

There are lots of reasons why condos are or become non-warrantableProjects where a single entity owns more than 10% of the total units (for projects with 21 or more units).Project has inadequate insurance coverage.Condo project has similar characteristics and is managed as a hotel (condotel)Project (HOA, sponsor, developer) is in litigation that relates to safety, structural soundness, functional use or habitability of the project.New construction condos.Established condos that have additional phases in need of completion.High percentage of non-owner occupied units.High number of units being delinquent on association dues for more than 60 days.Project budget is not appropriately structured.Does the condo budget doesn't have at least 10% in reservesDoes one owner own more than 10% of the unitsIs the investor ratio of the units greater than 50%and many more. 

@Yogesh BhadaneScenario 1, you are factoring in Depreciation and PITI.Principal is not deductible for tax purposes.Furthermore, you may be forgetting other expenses such as travel, utilities, etc.I am still confused how after depreciation and PITI, the number is positive $10,000 but net profits becomes -$100.how is a number higher when factoring in depreciation?
