I have 50k in equity built up and am looking to buy my first rental property, most likely a single family house.

Clearly at the time the land was divided and sold, it was considered acceptable to building houses on this size lots, even with septic.

If your farm is female or minority owned there is even more programs.  

The contractor is required to provide a 1 year warranty on labor and materials but replacement contractors are difficult to find because they have to warranty all the work ... even from the OG contractor. 

If I proceed with adding one unit, around 1500 sqft, the construction and approval costs may amount to approximately $450K, which would bring the total property value to around $1.35 million.Given that some three-unit properties in Canton have sold for less than $1 million in the last two years, I'm uncertain whether adding this one unit and renting it out would be a wise investment.My questions are:Is adding a single unit worth the investment considering the current market trends in Canton, MA?

It will spark conversations with people you didn't even think would have an interest in your services.You may be able to find a deal or 2 within your own sphere of influence.I see that you're a school principal so as long as it doesn't conflict with your position, I'd imagine that you have a lot of folks around you who trust you and your judgment.

Maybe a site even does the mailing for you or priovides a list you can mail merge yourself?

Oh $30k isn’t even all.

BiggerPockets also has a calculator you can use to analyze deals and I highly recommend you start this as soon as possible, even if you are not ready to buy.

Even if you don't want to go through their course, listen to their podcast and check out their YouTube channel.
