In FULL accuracy, the Fed operates neither as a governmental branch nor a private entity, they are something unique unto itself.

Heck, you should probably replace price to income with payment to income if you want anything approaching accuracy.

From the previous owner we obtained a plat that is quite detailed but does not seem to have been recorded as when I went to the county records office there was no plat found recorded for our lot nor for any of the neighbor's lots, although we did find one for the entire neighborhood development that seems to corroborate the accuracy of our plat.Our plat shows the upper corner of our chain link fence, near the house, on the lot line, but shows that the straight fence angles inward such that the back fence post down by the creek (back lot line) is some 19.6' in from the actual property line (a pleasant surprise for us).

If you saw a 20-unit building being offered at a 11% cap rate (based on prior year's actual expenses), but over the next 5 years it needed new roof, new parking lot, and new HVAC systems, how would you value the accuracy of that asserted 11% cap rate?  

The notice must include: the name, address and telephone number of the CRA that supplied the consumer report, including a toll-free telephone number for CRAs that maintain files nationwide;a statement that the CRA that supplied the report did not make the decision to take the adverse action and cannot give the specific reasons for it; anda notice of the individual's right to dispute the accuracy or completeness of any information the CRA furnished, and the consumer's right to a free report from the CRA upon request within 60 days.Disclosure of this information is important because some consumer reports contain errors.The adverse action notice must name the CRA that provided the report to the landlord, even if the information came from another CRA.

Then afterwards you will of course want to confirm the accuracy of what was represented to you (that you based your offer on) and get leases, tenant estopple certificates, etc.The seller would typically have X number of days to get you the required docs (after the date of an accepted offer), then you have X no of days to review and respond to any concerns.Appraisal almost always comes after an accepted offer.Prior to offer you might get:rent rollinsurance / taxes Utilities (and who pays what)

Required in your letter/notice:the name, address and phone number of the CRA (including a toll-free number for nationwide CRAs) that supplied the reporta statement that the CRA didn’t make the adverse decision and can’t explain why the decision was madenotice of the consumer's right to a free copy of their report from the CRA if they ask for it within 60 days FCRA § 612notice of the consumer's right to dispute the accuracy or completeness of any information provided by the CRA FCRA § 611the consumer’s credit score, if a score was used 

What is the purpose of tracking, is it to obtain  financing.If it is only for your personal enjoyment then accuracy is not important and not worth the effort.

I always remember what my engineering professor said about estimating, there is no wrong estimate, there is only degree of accuracy.

I am looking to purchase my first multi-family and was curious what others think about the accuracy of the 50% rule in a state with high property taxes.
