If you own several apartment buildings your best interest might be to speak with a asset protection attorney versus asking questions online of just anyone who might respond.Good Luck!

So, if you don't know how to build financial models, there are some available that are pretty good online (adventures in CRE is a great resource).  

The expert you are looking for is called a Land Surveyor, they're going to want 5k-15k, if you want to make any money on your project you need to build a house so you also need an architect, they will want 10k-50k, if you're in a hillside zone you will also need a geologist, they're going to want 10k, you will also need a biologist, they're going to want 2k-5k.

House hacking can reduce living expenses and build long-term wealth but won't provide significant immediate income.

Hi Calvin, if is it listed with anyone, it may have a similar address and a realtor posted your address by mistake,This happened to me a few months ago whereby I own a condo in a community that has 3 building and I own A6, but they were trying to list C6 and only added 6 to the MLS listing lol.

We are continuing to do regular flips and wholesale deals,  4 new builds this year.

Does that factor in both the mortgage, taxes and maintenance? 

I've included an example below to help illustrate this.So different lenders have different rates (which do vary even for DSCR loans) but these are factors they all consider.See example below:DSCR < 1Principal + Interest = $1,700Taxes = $350, Insurance = $100, Association Dues = $50Total PITIA = $2200Rent = $2000DSCR = Rent/PITIA = 2000/2200 = 0.91Since the DSCR is 0.91, we know the expenses are greater than the income of the property.DSCR >1Principal + Interest = $1,500Taxes = $250, Insurance = $100, Association Dues = $25Total PITIA = $1875 Rent = $2300DSCR = Rent/PITIA = 2300/1875 = 1.23If a purchase, you also generally need reserves / savings to show you have 3-6 month payments of PITIA (principal / interest (mortgage payment), property taxes and insurance and HOA (if applicable).

Since you have a primary focus on house hacking, saving money, building equity in your current investment. 

My realtor recommended SDIRA Wealth, a company known for its high-volume new builds every year.
