How much should I expect to pay for closing costs on each end - purchase and then subsequent sale?

@Karl Krentzel  As far as I can tell, all you needed to say to this thread was:- "When I buy off the MLS I am NOT utilising my Realtors license and am NOT getting ANY commission from the either the Sale TO me, or the subsequent Sale BY me.

Given these circumstances, I developed a strategy: buying a villa and its rent daily for 4 years with an income of 48-60 percent and the subsequent sale with a profit on the purchase price of 30% (my 20% discount for buying at the construction stage + 10% increase in value over 4 years). 

Cover the security deposit too - $xxx has been paid for the security deposit and will be returned to Sam at the end of the subsequent lease.

You can find a balance of being below market rent, but not losing a large portion of money and subsequent value in the property.

Subsequently, you can transition to long-term financing with a cash-out option. 

But if they will be difficult, then it won't be worth it unless the deal is so good that you and the subsequent assignee are fine, sight unseen, which is rare.

You want to make sure that you can use rental income to knock down your DTI and qualify for subsequent properties. 

When I contacted them subsequently (in 2012 or 2013) about potential roof work, they ended up sending someone from Durable Roofing, which I interpreted as an "overflow referral." 

@Richard Quijano You need a very reliable contractor to handle the construction and subsequent city inspections.
