I would argue that the development prior to that when as far back as 2014 for new construction.

If you have a remote lock like schlage encode,  you can enter the time the code will start and end , but give the guest the information of how to enter in advance, I think If I was going on vacation and did not have any info on how to get in prior to one hour  before check in that would make me a litte anxious and start my vacation with not so great vibes. 

Sounds like you work full-time in real estate and therefore should qualify as a Real Estate Professional - which was mentioned in several prior responses.However, you don't need to qualify for this status.

Being in foreclosure and buying after foreclosure are two different things. you could still do a traditional foreclosure and buy it prior to foreclosure.

There is no reason they shouldn't advertise the unit prior to it being vacant unless they have no idea of the current condition, which is its own red flag. 

Option 1a COULD be ok, but only if you can spend that $20k and add more than $20k in equity prior to sale which is no certainty when you're starting with a rent ready property.

It helps to prevent a tenant from doing what this tenant did and to give you remedies in case the tenant revokes the notice prior to the notified termination date.

Agents are required to submit all written offers unless seller has instructed them differently.

Prior to the disability payments, section 8 covered $900 of the rent and tenant paid $50My initial goal was to increase the rent to $1,200 assuming section 8 was paying.  

Also, we inherited that tenant when buying the property at a foreclosure sale and section 8 was very helpful in providing all documentation, last signed lease, renewal or rent increase instructions, inspection information, etc.
