Stay away from companies that have IMPULSE selling and try to get you locked into residual contracts that are hard to get out of.The companies I use for services I do not work on long locked in contracts and pay monthly instead.

The cash flow is comfortably paying the loan after expenses with some small residual.

@Jeffrey Kovnick The IRR is really just the cumulative cash on cash (CoC) return for the entire hold period, including the residual sales price.

We flew over in 2016 (my first time coming to the US) and Started all over from scratch in 2016 with $70,000 in his bank account only (residual settlement left from court proceeds).

Infested with Roaches and cigarette smoke residue.

If your willing to sell, not afraid To pick up the phone sell something that you get residuals on every year.

This involves taking the sales price of the finished home and doing a residual analysis which is done by taking the Sales Price of the finished home you envision on one of your lots and deducting everything BUT the lot price.

Your rent income minus all the monthly expenses (mortgage, property tax, insurance, property manager, repairs, vacancy, etc.) leaves you with $600 of residual income. 

I don't leave spray oils either because they tend to leave residues.

You could throw in a few air cleaners and run the AC for a few days and get rid of all the residue.
