A drastically shorter due diligence period and also an additional earnest money deposit for using an extension period were included by our broker in our counter-offer, but I really like the right of continued marketing clause, even with a ROFR, and will have to keep that in mind depending on how negotiations proceed.Thank you so much.  

In the end, the value of the deal comes down to a minimum, specific, monetary return, within a specific period of time.Here's an example:  I want all my cash back at refi on a rental$100,000              ARV in specific area based on Sales Comps$  80,000              75% ARV for refinancing$  75,000              Cost to buy/rehab$    5,000              Cash Out at Refi (bonus, bonus, bonus...)Here's another example: I want all my cash back at by the end of the first year on a rental$100,000                 ARV in specific area based on Sales Comps$ 80,000                  75% ARV for refinancing$ 85,000                  Cost to buy/rehab$      500/mo.           

is it a 1 year waiting period ?  

He kept the house as a rental for a period of time.  

In short, if you want a seller-carryback note created on or after January 1, 2014, if it is a private individual, trust, or estate, then ask them to sign an affidavit saying that they have not done more than three in a 12-month period and how many of them had balloons.

We were able to find one that has 3 bedrooms in each unit, but of all the 4 plexes we saw on the market in a 4 month period, we only found 2 that had 3 bedrooms in each unit in the areas we were looking.

Most wholesalers try to tie sellers up into as long of escrow period as possible.I know real cash buyers that are still closing in 10 days. 

We are thinking about buying and building out one to put temporarily on a property we are developing and rent it via Airbnb until we are ready to begin construction of the quadplex on that part of our land, and have it for sale during that period of time.  

Finding out after 4 VERY costly evictions over a 24 month period that something needs to change.(1200+ per eviction for attorney, + 3 months unpaid rent each eviction = average 4.2k per eviction = 17k loss over 2 years - not including the thousands in damage that was done)Business evictions are heard one day every 2 weeks and take  3 months, privately held every day and take 6 weeks on average.

This way, you know the contract itself is legit and you just need to worry about filling in the proper terms (i.e. your earnest money deposit, specifying your escrow/closing agent, giving yourself a favorable inspection period, etc.).
