mkuu ... hapa kuna mawili ..... la kwanza ni upande wa wateja wa real estate; kitu kikubwa kinachowawezesha wateja wa nyumba especially residentials ni system ya mortgage finance , sasa hapa kwetu TZ ndiyo inataka kuanza .... pili serikali imekuwa na very poor strategic plan kwenye idara ya urban planning, hakuna future planed towns, suburbs, townships and sub areas ambazo zipo in proper survey and with proposed infrastructures (water & electricity, transport;trains and roads, hospitals, markets, sports etc) ..... miji yote Tanzania imejaa na sehemu nyingi za miji tena mikubwa kama Dar (manzese) utakuta ni unsurveyed,
hivyo basi lazima uwe na enough resources ukachukue ardhi kubwa nje ya miji ,manispaa au majiji halafu ufanye township/suburb planing pamoja na infrastructures zake ndipo ujenge nyumba, apartments, shops, malls and offices for lease/rent or for sale..... au ununue viwanja kwenye ready developed satelite cities if you like in which the chance is very narrow for now due to small number of lots and high competition (kama vile vya Luguruni: wahindi ndio wameula pale)
you need big lot of money my bro ..! good business
unless otherwise i wish you all the best ....
