-AC Condensor Unit will be added this spring coming up.

If you're doing enough work to get a few individual trades reasonably busy you can probably find ones that will work cheaper than if you were hiring them through a GC who would be adding their overhead and profit to the trade cost.

Cash flow requirements, how much forced appreciation can be added, etc.2.

If you were to have this asset pre-marriage, then get married and build equity together, then divorce, it would be much easier to figure out your relative shares (pre-marital= all yours; marital share=50/50 split in most states and that 50% would be added to your pre-marital share).  

Purchase / sales expense - depends, some expenses can be added to basis, some are not deductible. 

While they might not be deductible before you finish out the purchase, once you complete the purchase of this current contract all the expenses you incurred during due diligence should be added as an expense against the property in your record keeping. 

Great post, At some point soon we'll be adding 100 doors within a month's time frame to subdivisions.

And the part of the principal that's attached to the shares you own can be added to your base when you sell, thus lessening the amount of capital gains tax you will pay.

Water bill is $30 per month and they will send in $100 to be added to their account.

@Jonathan Farber  At this point, you need to tell him that he's been there longer than a guest and either needs to find his own place or be added to the lease AFTER you do a background check on him (same as you did for the current tenant).
