House Extrapolated!

Posting some insight on Apartment purchasing power of Pune Techies.
Its however my personal opinion.
Dono if it augers well with others though.Anyways, here it goes:

Assuming 5 times of Gross income is Eligible Loan Amount,
I have created this table which is as follows:
Type.......... AgeGroup.......Workex in Yrs.......AnnualGross.......Max Loan Amount*
Fresher........22/23.................0-1......... 2.0 - 2.5........... 12
Programmer.....23-26................ 1-3..........2.5 - 3.5........... 17
Sr. Programmer.26-27................ 3-4..........3.5 - 4.5........... 22
TL.............27-29................ 4-6......... 4.5 - 6.5........... 32
PL/GL/Asst Mgr 29-30.................6-7......... 6.5 - 8.0........... 40
Project Mgr....30-33.................7-10........ 8.0 - 11............. 55
Sr Mgr/ DM.... 33-36.............. . 10-13........11 - 15.............. 75
Note that
#1. Salaries mentioned above are gross not CTC which is funny and useless number.
32. Salaries above may not be applicable for bluechips like Credit Suisse/JD etc.
Now, for derivations from this table:
A 2bhk at 35L, one has to be close to 30 agegroup to buy or has to have done a Onsite .
If Pune has 1 Lac IT plus Auto Pros ( max 25% of total ) and
50 percent can't afford. in current setup,
20-25 percent have bought 1 home atleast,
20-25 percent probably looking at oppurtunity to buy.
This prospective buyer population will be about 20K-25K max!!
Assuming a 12 storey, 4 flats per floor, a building has at max 50 apartments. For a moderate 5 building society, total number of Professional required would be 250 (50*5) , 1 per family supposedly.
If Pune has 25K Professional (IT plus Auto) looking for flats, then max 100-120 such societies should be enough for 2-3 yrs.
Anything more, there are investors who have bought won't be able to sell off easily.!!!!
Thats my extrapolation.
