Please see the rough numbers below :Tear down house price 350k,Construction cost 165 sqft * 2 build=627k Darnell, did you get your questions answered?

If you have a good FICO, a decent down payment and closing costs, go ahead an do the first one. 

This can be very expensive and is usually the worst choice because you can't justify the cost.2.

It costs the same amount to replace a roof or furnace whether the house is worth $300k or $30k (assuming a similar size).

Does a cost seg or bonus depreciation actually help you in any way? 

Quote from @Jeff Sanders: Personally coming from an agent/investor in CA, I always get a quote from a broker of mine and make sure I am knowledgeable with the fees/costs.

Trying to get a # from him about estimated remaining cost but got nothing.   

@Dhruv Patel I believe you are getting ahead of yourself....Where in the US are you all-in (land acquisition, soft costs, hard construction) on new construction multi-family for $100/ft.

The cleaning costs alone were over $9k.

At the end of the day; you need more money to do something like this.MAX LTV on new builds is 80% LTC, Meaning if the build is $550,000 and Land is XAdd ($550,000 + x ) * .8 = LOAN AMOUNTYou would need to come in with MINIMUM 20% of the cost in addition to closing costs and reserves, $80,000 is not going to cut it for this project.
