The companies that market themselves as "garage door companies" (residential) also almost always do commercial stuff as well, such as what you are looking at.

Any luck on if this company is legit, looking to use them for funding too.

That said there are some nuances and requirements to property implement interest tracing so ensure you talk to your tax professional ahead of time and keep the funds movement as clean as possible.

Facebook is the last place you want to find private money. whats unfortunate is real estate professionals are still advertising to us newbies Facebook is the place to find the lender.What’s even more unfortunate, @April Smalls, is that newbies are falling for it.A few years ago, someone created a fake website that impersonated our company.
