Very high interest rates, Easy times to find deals with conventional loans and hard times and recently the housing bubble / crash.  

@Alexandra Coryell this is going to be highly dependent on your lender and your builder. 

Much like fix and flip loans spiked up to 11-14% for a while, and are now back in the high 9's to 11's, I think it's encouraging to see the terms floating back to closer to where they were before. 

Are there any specific marketing channels or tactics that property management companies often overlook but can be highly effective in lead generation?

Do not paint brick -- low maintenance becomes expensive high-maintenance, no thank you. 

Regarding limitation of taxes upon selling, you'll need to make your expenses high (at least on paper), but if your plan is to purely sell it and cash out, then you're going to end up paying capital gains taxes.

As an agent if I get a referral I love clients who are A) Ready & able to buy B) They communicate 3) Not difficult/high maintenance.

As a PML, I generally like to have all my money plus a high interest within 6 months.

I highly suggest looking into duplexes in areas like Sunnyside, Acres Homes, Independence Heights, and East River.

High volume discounts are available to everyone, irrelevant of deal type, with me.
