Income Digs has great YouTube videos on how to tailor QBO for real estate investors if you're looking for a DIY approach or some education on it. 

I personally like "the quickbooksdude," "Hector Garcia CPA," and "Income Digs."

Please keep in mind that "suspended passive losses" or losses that are generated that are passive by nature, will STAY passive losses, and CANNOT be used to offset active income.

Overall the positives outweigh the negatives in my experience and what you lose in nightly rate you make up in occupancy/overall income and ease of management. 

@henryClark  owns property there and is up to speed with most things Belize.I was just down there in Jan. looking at some government sponsored low income housing where there were capital needs.

For example: 975k for an old (100 years) place with 100k income and 27k property taxes and owner paying $8,200 in annual utilities plus insurance and maintenance costs. 

Truthfully I couldn’t afford with of my duplexes without the rental income.

You are correct in your formula to make sure income covers expected costs.

if you do it right you can get your money out (and maybe a little extra), get some cash flowing for additional income and do it again.

The resoning behind this is that while capital gains would be at a lower tax rate, the interest is ordinary income is taxed at a higher tax rate.
