My time is limited right now because of my work schedule.

@Rupert GrantGenerally if you're eligible for a Solo 401k, it makes sense compared to a self-directed IRA for many reasons: Compared to an IRA, Solo 401k contributions limits are roughly ten times higher.There is no custodial requirement for the 401k.You don't need the additional expense and administration of an LLC to have checkbook control.You can borrow up to $50k from the plan; IRAs do not allow participant loansThere is a built in-Roth component whereas IRAs are either traditional or Roth, not both.A spouse can also participate in the same Solo 401k plan.The Solo 401k has additional tax benefits over an IRA when investing into real estate using leverage.The penalties for prohibited transactions are less severe, though it's best not to utilize this benefit :)The one exception I can think of is if your primary goal is to self-directed Roth IRA funds.

Most likely you will receive the most benefit from selling and deducting the loss but there may be limits to the immediate deductibility of the loss.

Keep in mind your homestead might be protected already (check for your state to see exactly the limits) and your retirement accounts also have their own protections.

They don't have to disclose flood zone here so you have to look it up individually, and some insurance companies have set up their own "surge" zones so either limits your choice of insurer or increases insurance costs in those areas.  

That doesn't sound very appealing to a developer especially 30 acres for a big project.Not all of the land may be developable anyways because of topography, streams, etc.First see if in county or city limits and land at current and future land use map and see what the area allows for zoning.

This is a declining market with 3 of the DC area jurisdictions recently passing legislation limiting how many days you can AirBnB a property, and limiting it to owner occupants only.

I would go for the best deal over limiting yourself to a specific type. 

Sorry i can't message you, at my 10 message per hour limit.

That said, you can have a clause in your lease that has a limit on how long a guest can stay, but you cannot prevent daily guests, unless that guest has caused problems and you filed some kind of injunction against that person.
