When investing in New Construction, you are controlling the property for the first, BEST years of a buildings life.  

Instead, have your family record a private note on your existing property.

A couple of my investors are looking to invest in this particular market and just looking to get an idea of the average price per acre for large rural farmland properties.

by that time they had burnt down the trailer on the property, not paid rent in months, let the land go and made a mess of things. 

I have one duplex and have been house hacking since I bought it, it's been 5 years plus I have this property and finally ready for a 2nd one, looking to see if I get another multi or a single family, any thoughts Side note I also need a bigger place since I have another child who now needs their own room.

Not only do most property managers have tenant procurement packages, but you can allow self-showings.

For example, I believe Nest and Ecobee digital thermostats allow you to put a low/high floor on the temperature so tenants can't put it below or above a certain temperature.Finally, your lease should include a clause that says tenants are responsible for repairs if they abuse or neglect the property.

Then, on the day of closing, the buyer revealed a major issue: there was a second loan on the property, an additional $60,000 over our contract price.

I work with investors every day that are finding our off market new construction investment properties are a great way to invest.  

Since you are new to this you may want hire a property manager to handle managing the properties for you.
