Are they just referring to owning a business period for write off's, or are they referring to strictly Corporations?

Sounds like you able to get the higher appraisal (and get all your money out) partly because of appreciation and not strictly due to the rehab you did to the unit.

I’ve been down this road and they are very strict about this .

A bank is very strict and the deal has to fit in this “tiny little square box “ but land contracts allow for infinite options with less down and sometimes no interest at all .just depends on how bad they want to sell

So my question is approximately how much of a mortgage will i be able to be approved for if i am putting 20% down and the property is strictly an investment property?

Does any one have sample lease forms that mentions clearly that the lease is strictly for airbnb?

I would love to learn more about this process, such as do these homes need to be primary residences, vacation homes, strict rental properties. 

@Samuel Brand  This is strictly a personal / risk-tolerance decision on my part, but I would not own a rental in Mass. 

Would you strictly start with multifamily investing? 

It is significantly better than SD IRA for the following reasons: Custodian is not required = no custodian fees, no asset-based fees, no transaction feesCheckbook control over your retirement fundsNo tax on leveraged real estateAbility to make large contributions: up to $61,000 annually Ability to invest tax-free using Roth account The property owned by your 401k can't be used by you personally, has to be strictly investment.
