Building castles in the sky or meaningful relationships with a local realtor is not the way to get a great deal or retain your sanity .

I’m also a little unsure of what exactly would be considered under the repair cost as from the book I’ve been reading they just call it wear and tear of living like scuffed floors and banged up walls.

I've sort of hit a wall with deal analysis and I'm having a challenge keeping myself accountable. 

What added more value to this property is that I re-finished the basement by turning it into living area: new windows, outside door, new walls and flooring.

Two bedrooms would be more effective,  just a divider wall and an extra closet and window.It is 375-450 square feet ?

an LC is a form of owner financing, like any other, the seller retains the deed till the contract is fulfilled if you dont hold up your end, the seller has the right to the property back as liquidation for damages, just like a mortgage. 

If a new client's website takes much longer to load and retains 20 percent or less of visitors, you may want to ask for an increase in your minimal PPC budget.

On top of that every time I go there is something broken , a door, a wall etc .

For local maintenance and handymen, I think you may find a bit of trial and error, but there are a few local services who will do "as needed calls" and who also offer a retainer based contract after so many units.

I have seen people online switching to insulated concrete forms (ICFs) for the foundation and walls instead of traditional framing to save on the costs of wood.
