Ask away. you have found a treasure site and if you follow much of the information here eventually, you will be prosperous. 

Even a single family builds can vary significantly based on site conditions and required structure/design.

If you determine that the numbers look good, make sure to check other sites to see if the comparable property is on multiple sites that may add to the numbers.  

10 years ago my property was 90% VRBO, 10% Airbnbsame property 10 years in using both,now it's 90% Airbnb, 10% VRBOsame property, same pictures on both sites, etc.

You have to know your state landlord-tenant laws; they are on the internet:"In New Jersey, a landlord may need to give a 30-day notice to pay rent before eviction if the tenant has a history of late payments and the landlord accepts them.

I’m even considering buying thick rugs to give the tenants above but even that sucks to have to tell tenants what they need in their home.I really love the community on this site.

Do they require payment on site or do they give you a certain number of days to close the transaction?

There are 4 Single Family Homes built on the site. 2 are built-to-sell and 2 are built-to-rent.What made you interested in investing in this type of deal?

As for numbers, I currently owe $86,151 on the mortgage, and on Zillow it is listed at $143,600 but the numbers seem to be inflated on that site.  

The "retire off of real estate" crowd on the internet mostly spouts nonsense or has something to sell.
