I think you are looking at the wrong places, insulating the floor wouldn't change much. 

Cold calling IMO is the easiest way to get into the space.

My wife and I just closed on a duplex in Oakland, but the basement/garage was already converted into a separate living space with a bedroom and bathroom.

@Jason Wray, The reason that our shop is pretty hot about your post is two-fold, we do all of the things that you are implying that we don't (other than government loans, we don't work in that space). 

It's that simple.Doesn't hurt to have real hardwood floors and A/C as well.

While the interior is nice, the first-floor kitchen and bath are original from the 1940s.

When we spoke, I alerted you to the need to make the quick repairs, and you agreed to allow access to the space to get things back to top shape.

Painting and flooring are super easy.

I Joined Jeromes Buying land and building homes program back in 2019Heres my opinion on my experience....First and foremost He offers two different programs. a 6 month program and a 12 month program.BOTH PROGRAMS ARE EXACTLY IDENTICAL THE ONLY DIFFERENCE IS:You can choose to have the weekly mentoring by Jerome once a week for 6 months or 12 months on a zoom call and you can have access to a private networking group of real estate professionals whether that be (realtors, contractors, brokers, Private/Hard money lenders, loaning institutions, Surveyors, Engineers, Zoning Board members in different municipalities, pretty much anyone you would need to get a project completed) for either 6 months or 12 months.6 month program will run you $5,997 if you decide to pay all at onceor you can make a $2,300 payment every 2 months totaling $6,90012 month program will run you $9,997 if you decide to pay all at onceor you can make a $3,000 payment every 3 months totaling $12,000I decided to join the one year program and chose the payment option as i figured within 6-8 months i would have my 1st project completed therefor my last two payments would essentially be covered by the return on investment from that project.PROS:The group is really a family oriented space where you meet a vast variety of people from all types of background throughout the country and other countries that are doing business just like you.
