I've been using the average of the 3 lowest and 3 highest comps in a one mile radius if possible but I'm finding that in some areas that is a big gap and I'm trying to find the most accurate way of estimating value short of calling a Realestate agent or appraiser for every deal I analyze.

Still learning though and gather information and building network.

I gathered those numbers from comparable units.

Was hoping to gather some information and referrals on both attorneys and mortage brokers that other readers truly recommend. 

Hi Community,Short Term Goal: Leave Rent Free , stay in one part of Multifamily/ room in Single Family Home and rent the remaining using FHA/Conventional with 3 to 6% deposit.Info Gathered : Orlando Area, Clermont, Davenport, Winter Garden, Winter Park, Hunter's Creek,Celebration.Looking For : Places to Invest and rent the part of the home for students / professionals near Kissimme 34747 .I am ok to invest 100000-250000.1) Which area is the best for better ROI and why?

It is difficult to get accurate information on smaller properties.

It is more management on your part and I'm not sure how to manage it but you could have an option to rent out the whole thing for family gatherings but have individual units available when the whole place isn't booked. you would need to be careful to not overbook it.

Estimated numbers which we hope are accurate or too high:4.3% 30 year mortgage for 80% of the purchase price. $9,000 closing costs. $1,500 per year in repairs/maintenance. $3,600 per year for electric/water/sewage (they pay heat/cable)$400 put aside each year for future capital expenditures (should this be higher?)

Is this accurate?

And every calculator would put monthly payments at around 800 to 900/month.In the future, when I see a  home  that I want to jump in and purchase, how can I accurately calculate what my real monthly payments will be?
