Isn't a pay or quit typically 3 days?

The best analogy I can think of is asking someone to put together a great baseball team and defining the terms average, home runs, and RBI but without any context of what typical numbers are.

But typically buy townhomes...so the only people the tenants could complain to would be their own family members living with them. 

Less hassle in the long run and you never have to worry about a tenant letting it run out and freezing your building.If you do end up keeping a separate furnace for each unit just be aware that propane tanks are typically supplied by the fuel provider.

Interesting - the market in Huntsville right now has not slowed down at all;  in fact, I would argue it is even crazier than it was 3 months ago, and is now virtually impossible to find a property to cash flow unless you go to C/D neighborhoods or go in areas that typically have zero appreciation (outside of Huntsville and Madison city limits).    

I doubt a typical lease would allow a tenant to add vending machines.

It not only typically keeps you in the same place for too long and not being mobile enough to go to the best market. 

We're typically in Fort Worth and surrounding but would like to network and build some relationships in the Dallas area.

@Keniya LeeWatch for Philly laws but in pa to my knowledge you typically put up a quit or pay notice on 5th and can fIle evict papers on 15th .

What you will find is that there are more duplexes that will attract professionals as tenants than four families: moats have been built as affordable housing in clusters and are typically 1 or 2 bedroom units.
