Every construction loan I know of requires significant cash or pre-existing equity in the deal (my bank requires 20% of total costs) when it comes to investment properties).  

Any pre-existing, weird / messy roommates will make the good ones miserable or refuse to sign.

They have a 5 year rule on pre-existing conditions though.We are taking a calculated risk because we are both young & healthy until we can move to Oklahoma next year & get state insurance for $65 per month.

A lot of multifamily apartments are bought via syndications and most syndications are structured under SEC Regulation D Rule 506(b), which requires that you have a pre-existing substantive relationship with your investors.

@Roni Elias Often times GPs are taking LPs through questionnaire to make sure they have a pre existing relationship (per SEC) so to me this would be welcomed from the GP side.

You'll need to either have a preexisting network of high net worth individuals or leverage past experience to raise capital (plus put together a credible, experienced team).

The amount of premium you pay monthly could be averaged over the total duration of your mortgage or can decrease based on the amount left at risk.Like most term life insurance, they are usually cheap (if you are reasonably young and have no preexisting medical issue).

Now, you will find that building is SIGNIFICANTLY higher cost than purchasing a pre-existing home. 

Too many way to list here, but the main way was to leverage the pre-existing customer base and add inventory.

Agents primarily are perfectly fine, "filling in the blanks" of pre-existing documents; and drafting simple Rental Agreement amendments such as basic renewal letters.
