Determine how much you actually pay each month toward your HELOC to pay it off in 10 months (I know that can be a bit of a challenge if you put your paycheck in there and then pay bills out of it, but it's doable).

It's all doable but know what you are doing and have the time and energy to do it. 

It unlikely that I will concert that but its doable and I am calling the zoning just to check it out that possibility.Darryl - I have no clue how much difference it will make.

I'm from Youngstown and I live in Youngstown it's true - That's about the range also - $10-$30k And rents between $600 and $750 - You have to buy in the right areas but it is very doable - Because I was born and raised here I know what areas to buy in - I would say a good price is around $40 to $60k with  little rehab you can have a long time tenant - If you need any further help let me know 

So, evidently it must be doable and in the greater sense, profitable.

And anyone who doesn't show up or shows up late, or wants to see it another time, well, you snooze, you probably lose.  

The price-to-rent ratios in our part of California just weren't do-able.  

@Joseph Lewis, Although there are some landlords that do quarterly inspections, every six months is doable for most tenants, and, yes, you will definitely want to include wording about doing inspections (necessity and cooperation of the tenant) in your lease agreement.

Eviction is not simple, but it is doable and it is part of what we must sometimes do in this business.3.

It has been prevailing wisdom that 6 units while working FT is nicely doable.
