THREE MONTHS ENDED SEPTEMBER 30, 1998 COMPARED TO THREE MONTHS ENDED 
SEPTEMBER 30, 1997

Net sales for the three months ended September 30, 1998, increased by 53.0%, to
$63.8 million, from $41.7 million for the comparable period of 1997.  The number
of homes closed by the Company increased by 46.6% to 415 homes for the three
months ended September 30, 1998, from 283 homes during the same period in 1997.
The average selling price of a home increased 4.3% to $153,700, during the three
months ended September 30, 1998 from $147,300 for the comparable period in 1997.
This increase was due to an overall increase in prices for homes sold by the
Company.

Gross profit increased by 73.2%, to $9.7 million for the three months ended
September 30, 1998, from $5.6 million for the comparable period of 1997.  Gross
profit as a percentage of net sales increased to 15.2% from 13.6% primarily as a
result of steady material and labor costs in the current quarter versus sharply
rising costs in the prior period.

Selling, general and administrative expenses increased by 33.3% to $6.8 million
in the three months ended September 30, 1998, from $5.1 million for the
comparable period of 1997.  This increase is due to an increase in variable
costs related to the increase in revenue during the quarter.  As a percentage of
net sales, selling, general and administrative expense decreased to 10.7% for
the three month period ended September 30, 1998, from 12.3% for the same period
in 1997.

Interest expense increased to $699,000 for the three months ended September 30,
1998, from $440,000 for the comparable period in 1997.  The increase in interest
expense is primarily due to the Company terminating capitalizing interest on a
piece of commercial land that it has held for approximately ten years.  The land
is currently for sale and has a book value of about $9.0 million.  The Company
capitalizes certain interest costs for land development and includes such
capitalized interest in cost of home sales when the related homes are delivered
to purchasers.

The Company's effective tax rate for both periods was approximately 41%, which
reflects the federal statutory rate plus state taxes, net of federal income tax
benefit.

SIX MONTHS ENDED SEPTEMBER 30, 1998 COMPARED TO SIX MONTHS ENDED 
SEPTEMBER 30, 1997

Net sales for the six month period ended September 30, 1997, increased by 36.4%,
to $115.1 million, from $84.4 million for the comparable period of 1996.  The
number of homes closed by the Company increased by 28.3%, to 762 homes for the
six months ended September 30, 1998, from 594 homes during the same period in
1997.  The average selling price of a home increased 6.3% to $151,100, in 1998
from $142,100 for the same period in 1997. This increase was due to an overall
increase in prices for homes sold by the Company.

Gross profit increased by 41.9%, to $16.6 million for the six month period ended
September 30, 1998, from $11.7 million for the comparable period of 1997.  Gross
profit as a percentage of revenue increased to 14.4% from 13.9%, primarily as a
result of steady material and labor costs in the current six months versus
sharply rising costs in the prior period.

Selling, general and administrative expenses increased by 22.8%, to $12.4
million in the six month period ended September 30, 1998, from $10.1 million for
the comparable period of 1997.  This increase is due to an increase in variable
costs related to the increase in revenue during the six months.   As a
percentage of net sales, selling, general and administrative expenses decreased
to 10.8% for the six months ended September 30, 1998, from 12.0% for the same
period in 1997.

Interest expense increased to $1,416,000 for the six months ended September 30,
1998, from $720,000 for the same period in 1997.  The increase in interest
expense is primarily due to the Company terminating capitalizing interest on a
piece of commercial land that it has held for approximately ten years.  The land
is currently for sale and has a book value of about $9.0 million.  The Company
capitalizes certain interest costs for land development and includes such
capitalized interest in cost of home sales when the related homes are delivered
to purchasers.

The Company's effective tax rate for both periods was approximately 41%, which
reflects the federal statutory rate plus state taxes, net of federal income tax
benefit.

LIQUIDITY AND CAPITAL RESOURCES

At September 30, 1998, the Company had available cash and cash equivalents of
approximately $438,000.

The Company's financing needs depend primarily upon sales volume, asset
turnover, and land acquisition and inventory balances.  In December 1994, the
Company issued $25 million of 12.11% Senior Notes payable and in February 1996,
the Company issued an additional $10 million of 9.42% Senior Notes payable
(collectively referred to as the "Senior Notes").  Proceeds were used to retire
certain mortgage notes payable and for working capital purposes.  Principal and
interest payments of approximately $552,000 are due monthly from December 1996
through December 2004.  

At September 30, 1998, the Company also had a $23.0 million revolving credit
facility from a commercial lender.  Borrowings under this facility's line of
credit totaled $15.7 million at September 30, 1998.  The Company has the
capacity as of September 30, 1998 to borrow an additional $10.0 million of
short-term debt, if otherwise available, without violating the terms of the
Senior Notes.  The Company believes those amounts available under its existing
borrowing arrangements (assuming extensions and renewals of debt in the ordinary
course of business) and amounts generated from operations will provide funds
adequate for its home building activities and debt service.

Due to lower than expected financial results in the fiscal year ended March 31,
1998, the Company was not in compliance with certain covenants under both its
Senior Note agreements and its revolving credit facility.  All of the Company's
lenders have agreed to waive the violations and in addition the agreements have
been amended.  Certain financial covenants have been reset over the next fiscal
year in order to give the Company time to reach original covenant levels.  The
Company will pay an additional $100,000 principal per month amortization on the
Senior Notes for the remaining life of the notes.

The Company has generally been able to secure financing for its acquisition, 
development and construction activities, and management believes such 
arrangements will continue to be available on terms satisfactory to the 
Company. There can be no assurance, however, that continued financing for 
land acquisitions will be available or, if available, will be on terms 
satisfactory to the Company.

YEAR 2000 ISSUES

Key financial information and operations systems have been assessed and plans
developed in order to solve the Year 2000 issue.  These plans revolve around
upgrades of purchased software.  These projects are substantially underway and
are on schedule for completion between December 1998 and April 1999.  The
Company believes that the costs to address the Year 2000 issue will not have a
material impact on the Company's financial condition or results of operations,
liquidity or cash flows for any year in the reasonably foreseeable future.  The
Company intends to initiate during fiscal year 1999 a communication plan with
significant suppliers to determine the status of their Year 2000 issues and does
not currently anticipate a material impact on the Company's operations and
financial results.  However, if such upgrades and conversions are not made, or
are not timely completed, the Year 2000 issues could have a material impact on 
the operations and financial results of the Company. 


INFLATION

The Company, as well as the homebuilding industry in general, may be adversely
affected during periods of high inflation, primarily because of higher land,
material and labor costs.  In addition, higher mortgage interest rates may
significantly affect the affordability of permanent mortgage financing to
prospective purchasers.  The Company attempts to pass through to its customers
any increase in its costs through increased selling prices, and to date,
inflation has not had a material adverse effect on the Company's results of
operations.  However, there is no assurance that inflation will not have a
material adverse impact on the Company's future results of operations.
