While she was gone I ripped apart our bathroom, and the only trick was putting it back together before she came back :) On other occasions, we've "tag teamed" ...

And I know it is not good practice to not account for property management in the expenses, but at the outset (early years of ownership for our first few properties) should I discount expenses based upon performing our own property management to add the 10% property management to our cashflow?

Repairs: 10k for cabinets, bathroom vanities and exterior/interior paint.

Property prices in my area which consist of 4 Bedrooms 2 bathrooms start at £250k, I believe.

If that day is the day your calling to buy, your the lucky winner getting a huge discounts.

House is part of a large Golf community, and renters can pay $15/mo for access to community pool, tennis courts, golf course discount, horse stables, yacht club.My wife and I are engineers and max our 401k's. 

Any electrical, plumbing, bathroom remodels, kitchen remodel, removing walls, siding, windows, roof, just to name a few.  

The home would likely have to be discounted at least the amount of the liens/taxes on top of whatever else they're looking at (or other concessions will have to be made by the seller) or else the additional lien/taxes might make the numbers not work for a good deal.

Bonus if they have a military discount.

Brokers add middle man fees... to wholesale interest rate prices that are already discounted.
