Is the minimal lot size available without altering current property? 

We already had a de minimis $2,500 exception, and now we have 100% bonus, and Section 179 is now available to landlords.

Those are the best teaching moments available to our team. 

The webpage will have answers to every question that I get from prospective tenants concerning the property (price, number of bedrooms, when it's available etc etc).

We have about 60,000 left available on the HELOC, however, I wouldn't want to tap into anymore than about 40 of that, in order to leave a pretty significant buffer in the event that something goes sideways. 

isn't all of this info available from a title company? 

It is amazing how much knowledge is available here and I sincerely hope that what little knowledge  I contribute is valuable to some.

There are a few other property management tools available but I'm really looking for a one software solution.Does anyone use AppFolio?

We would be happy to grab some coffee sometime if you are available and give you some options.

Another issue which the OP didn't bring up was how available property in NZ differs from other markets (notably USA).
