My other side would say "If you want to control your life, pay the cost, take the risk, buy your own house and have two bathrooms" but that isn't nice, so I try to stick to my pleasant negotiator side. ;-)

The house is needing some repairs, but have not physically looked yet.

Thanks for the advice  @Will GastonThis is my first house and I hope to be in real estate for the long haul so Ill take your advice! 

I am about 30 minutes north of Boston buying a house in a town called Lawrence, MA. 

The August 2024 report from the Austin Board of REALTORS® shows housing prices in Austin and the greater metro have been fairly stable over the past 12 months.

Some cities worth considering right now include Tampa, Charlotte, and Austin—all experiencing growth and increased demand for housing.

One of my biggest questions is could I sell that second house on its own once it's built?

This is the stage of the process where your lender can issue your loan docs out to escrow/title/settlement and these folks can schedule your signing for closing.Before it can reach CTC you'll need to make sure all income/assets/credit remain the same so that means no changes to your credit that are bad or adverse, no job or income changes ideally, and hopefully those funds you've set aside to close with are still "there," so we can keep this closing on track.If you had any questions left feel free to fire them off.

the appraisal should have considered the deficit and wether it was actually one on, like just sold, housing.  

Poor tenants cannot obtain quality housing.
