Grade of property prior to reno was decent (approx C+/B-).

If I'm in your shoes, I would advise on letting tenants know that lease reviews will be conducted prior to lease ending so they're not too caught off guard during renewal period.

Even if half the board is sold (supply is down) but the money supply dries up significantly - you are not going to pay what you would prior.

We were conservative on the offer price at that time cuz we were before a turning point and it wasn't clear at that time where the market was going to head towards, and the seller had a higher appraisal prior during the summer.

For us, that is 180 days prior to the lease end date!

We are trying to find a keyless entry door lock that you can automate to change the passcode whenever a guest checks out and also automatically send the new code to the next guest a few days prior to their check in.

Thank you I was also wondering if After i obtain my llc will i be able to get loans with no prior business credit history or do i first need to build my business credit history with credit cards? 

Sure, some modern building methods are far superior to what was used in the past, but lots of building methods used today aren't nearly as robust as in prior generations (ask an experienced GC). ....Additionally, a new house is still in its "growing pains" phase, and a lot of serious problems can emerge in the first few years of ownership--e.g.; foundation/structural settling, improper water diversion systems creating rot, etc. 

So in HI we start the process immediately after the closing, but we have paperwork and everything established 3 weeks prior to closing.

Prior owner needed funds and I bought at a discount for cash How did you finance this deal?
