In fact, it's a usually big red flag when someone has an aggressive move in date like "I need to move in tomorrow" or "ASAP".

About worrying about permits etc.And tax issues.Thanks Have options just don't want IRS red flags And insurance issues while rehab going on w/ tennants there as well.I'm under rental mkt.

Plus we invest in red states so we have good landlord laws on our side too.I started with turnkey remote rentals in 2009-2015 while working my engineering W2 job.

My plan was to first present the owner with Loan C in red, and if it's not accepted we can either go with Loan B or Loan A, with Loan A being his initial offer. 

After we move out, we rent it out (long-term rental)I know a LOT more research needs to go into these to actually say whether they are viable or not (market and deal analysis), but I'm hoping for some guidance as to whether there are red flags or green lights in principle with any of these three scenarios (4a-c).Thanks in advance for any advice!
