From there I've repeatedly used slightly edited versions of those same docs on multiple subsequent private lender funded transactions.

I have since acquired my own real estate sales license and subsequently broker license to start, grow, and operate Home Roots Property Management.

And would you invest the money to do the performative deep cleaning knowing that subsequent tests would likely show  the same levels after all was said and done?

Engaging in the process led me to investigate real estate investment and subsequently to BP.

@Tom S.1) Under the IRS multiple loan rules there is a 12 month look back period (see reference to 12 months in the IRS post) whereby the highest outstanding balance of any loan during the prior 12 months will be considered outstanding for purposes of calculating how much you can take on a subsequent loan. 

The answer is clearly yes, not to be fair the 2010’s were probably a golden age for re investing, this is an especially tough period, so that gap feels huge, some of this is just a result of the pandemic and subsequent inflation, some of this is by design, the Fed wants to restrict investing and for you to put money into tresuries and cd’s not real estate & stocks.

Unfortunately, their deduction was disallowed following an IRS audit and a subsequent visit to Tax Court.

On your subsequent tax returns, you'll list the property as an income-producing asset, you'll take your depreciation, and you'll declare any income that you generate from the rents. 

Subsequently, after establishing a balanced relationship with the tenant, you can consider making upgrades to the landlord's apartment,as a sidenote: Should any usable items be removed during renovations, offering them to the tenant can foster goodwill and enhance the tenant-landlord relationship.

Typically an REI veteran is going to have many posts on here and subsequently more money in the bank or maybe more savvy ways to fund their deals and would not need a service like fund and grow.
