My understanding is that any investments made from your IRA need to be passive in nature.

Because you've owned that land for a period of time and have not changed it's nature other than legal entitlement and identification I don't think you'd be tagged as creating inventory.So there's some options for you to pursue.

If that is the case, you cannot simply install a circuit breaker with a higher amperage, since the wires will not be adequate to carry the load. 

The biggest problem with all of the ebuying and things of that nature is that the buyers don't know what they don't know until it's too late.

3: Build 1 bedroom units as roommates become a liability-  (so build smaller units as price is a factor)4: Antibacterial materials on items you touch- (Metal is naturally antibacterial over time) some more than others- which is best?

If you start to get close to the average/median days on market you should consider a significant enough price reduction as long as you feel your Realtor is doing an adequate job keeping up with marketing.

The nature of the CoC depends on the size of the downpayment.

I feel that it would be more beneficial to just put yourself out there on here (your success, failures, dreams & aspirations, things you've learned) and the people who are meant to help you on your RE investing journey will naturally gravitate to you.

The vision is by nature limited. 

., so my comment is more generic in nature.
