Points charged by the lender (wouldn't you only get this once the bank has the property info), Cap rate, closing cost ( I normally estimate about $5-8K but if you are doing a rehab loan wouldn't it be different?).

We are very interested in a Buy and Hold strategy.I do have some basic construction skills, so I can spot things in homes we are looking to purchase and estimate how much it might cost to repair.  

Also, it has been my experience that by putting a larger down payment on a property the lenders will go ahead and count what that property is going to earn, in their estimation, towards my income, mostly offsetting the impact to DTI, or any negative impact that a purchase would have on my DTI.

At estimated $1300 a month for a 3 bedroom in Glen Burnie

Here are photos of the exterior of the house, there is concrete around the perimeter of the house and the entrance, budget is tight and have plenty to do inside so thinking of just repairing the concrete and staining it to give a natural stone look (taking out the concrete, dumpsters, labor and new pavers would be a big expense) However I read that newly poured concrete has to cure 90 days before you can stain it, is that accurate, also what is the estimated cost to stain outdoor concrete Per square foot?

@Rob Barelli, we use 1st American Title Closing Calculator to estimate our costs.  

Thank you Bill for the insight. what I'm actually looking for is an estimate of what it will cost me per square foot  to take on an addition/pop top project in Denver right now.
