There are time-sensitive things and when you are under contract on a property you can't just disappear.  

My personal opinion is I receive rent income for the rent of the property and there is solid client basis seeking to rent the property, I don't need to use my power as landlord to offer some complicated "buy here, pay here used car lot whose true business is in repo'ing those cars from the poor as soon as they default and restart the process".Please don't feel this is any form of an attack, I am simply sensitive to the blighted reputation of landlords - contracts such as this are one of the legit reasons the public doesn't like us. :)Lastly - I have sold several homes to tenants...I set them up with a bank who typically pairs them with a credit repair specialist...the tenant can buy the house at any point when they are ready at the market price whatever that is when they are ready (if the home appreciates then I gain, if the market were to crash like in 2009 by 60% I would decline sale and facilitate the the tenant in purchasing something on the market) .

Most private lenders aren't rate sensitive, but are rate conscious.

It is possible there is a malfunction that short cycles the system, or, the tenant is just overly sensitive/demanding.

And when pulling comps especially now we're ultra sensitive to sale date.

There are other strategies/alternatives to 1031s which arent as time sensitive

I would like also to be able to have sensitivity analysis on key variables such as rent, vacancy, interest rates, expenses, taxes, rehab expenses.. etc.

It depends on your credit profile and needs.A quick run-down of banks vs. private lenders:Banks- Lower cost (interest rate, fees, points)- Possibly lower leverage (LTC/LTV)- Need to find a bank comfortable lending on SFR fix & flips- More stringent underwriting processes- SlowerPrivate lenders- Higher cost (interest rate, fees, points)- Possibly higher leverage (LTC/LTV)- Less stringent underwriting processes- FasterIf you’re a creditworthy, cost-sensitive borrower, then you may find working with a local bank beneficial.If you’re less creditworthy and not as concerned about cost, then you may find working with a private lender beneficial.In any case, it probably makes sense to develop relationships with both types of capital sources if you plan on doing more flips down the line.Best,Michael

Obviously, it is not in my or the tenant's interest to go through the eviction process but my girlfriend is sensitive to the marijuana smell and I don't want my tenant's boyfriend to be conducting activities that is in violation of the lease.

This works OK for relatively static and simple investments like a private placement or crowdfund, but can become rather cumbersome and expensive with a more time sensitive and transaction intensive asset such as a rental property.
