How do you decide on the number of tenants able to fit in one property as I know its more complex than purely bedrooms, not speaking about legality's though.

Amit,     I would advise you not to invest in PS if this is purely an investment decision.

With the 2 and 3-flats, you're at the mercy of comps, which is pretty much pure speculation.

It is a pure commission sale “job” where the salesman must (1) pay for his own education (2) pay for his own leads (3) front his own money to put the sale “under contract” and put up his own money to pay all related expenses.  

My property managed used that and, by pure coincidence, I have heard about it in the BP episodes and I use it since it's included in the BP Pro membership. 

In the process of BUYING a PURE Option to buy a SFH subject to an existing loan (at a lower fixed long term interest rate)Let say the OPTION "Strike price" to BUY the property IF or WHEN the OPTION is EXERCISED is $300K The seller wants $60K to sell us the OPTION. 

In that asset class you are depending on things to save you that are trending against it.That said if the 30k completes a partial done rehab it might make sense but if it's a purely cosmetic one I would sell it now close to as is.

(Also, the developer is reasonably experienced + wealthy and has personally guaranteed some of the existing development projects - but wants to move away from that)I'm also planning to get some equity in the JV / the broader development company (much less equity than if I were to be a pure equity investor of course). because I do think this could scale to 300-400 homes / yearOf note: These homes are modular in nature - so are faster to build and margins are projected to be attractive.My questions for you all is:Have any of you lent to development assets with cross-collateral from cashflowing properties like this?

But since private money is relational based versus purely collateral based, you'll need a track record to prove yourself.
