Would it make sense to utilize the equity in the home toMove forward for purchasing our first investment or should we leave our main property’s equity alone?

Second, the cost of materials is soaring, but hasn't yet stopped the demand for a new home on the buyer's side.I know for certain that some banks are flipping houses now, rather than sell off their REO properties for discount.

If so, doubling expenses to 31k including vacancies, repairs, 2x utilities would put it at a 11 cap rate.I would estimate lot rent as $350x 60m 189kAnd each home at 29k x9 261kTotal 450k, and these numbers are on the high side.Cap rate at 450k and most aggressive expenses including 10% vacancies and 10% repairs is 14.7Was appraised a few years ago at 550k before 20k homes flooded in our parish, and these were not one of them.

With all useable land and fertile land(With the exception of Grand Oaks which cannot be cut down; which may serve as an attractive part about the "Community" if several homes were to be built on the subdivisions),  2 water wells, 2-inch water meter and all the utilities; how difficult would it be to find a developer to pick this up, have the deal assigned to, pay closing costs, and pay in cash?

In CA your primary’s mortgage interest and real estate tax benefits will be materially reduced beginning this year by the new RE/SALT limits.

The the boiler is natural gas so I am looking for estimates on how much it would cost to install new gas lines, a new boiler, and then a second breaker box etc for the electric to separate the utilities amongst the apartments.

They include (but not limited to) any loan payments, taxes, insurance, utilities, HOA fees, etc,. that occurs during the Rehab period and up until the property is fully rented.Hope this helps.
