If the seller mentioned that the HUD loans have no interest or monthly payments, this might be accurate for certain specialized HUD programs or subsidies.

Accurate due diligence?

@Timothy Stripto generally I would say numbers are fairly accurate, but with all real estate there is some variance. 

Major player is not anything I would consider to be an accurate description of him. 

After paying closing costs, title fees, appraisal, origination, underwriting, processing, legal and other fees, the typical refinance costs about 1.75 - 2.5% of the loan amount just in closing costs (obviously before people yell at me, this varies drastically by state, but having done loans all over the country I find this to be a pretty accurate estimate).  2) Keeping the average 2% cost in mind and the fact that people typically refinance when rates drop about .75% - 1% or more, I wanted to see if paying an extra point now when I was already paying all the closing costs to buy the rate down made sense. 1 point can get you between .5% - .625% off the rate depending on the days pricing and the coupon you are pricing. 

Mostly because it was so thick with stuff that you really couldn't even walk through the property to make accurate project estimates.

Everything you said is accurate.

You can save money and be able to check off certain items related to management with software, but how accurate are they?

If the software is not simplifying your life or making you more accurate, you shouldn't use it.

Let them help you with comparables, recommendations for the types of rentals that do best in that area, and maybe even connect you with a local contractor who will be able to get you an accurate (ish) estimate on required repairs.
