You could also potentially look at a line of credit if you have enough equity in the properties, but again that would require appraisals. 

I personally have a number of HELOCs on my properties, and as a lender with access to dozen of investor's HELOCs I can say none of them restrict the use of the HELOC, or even require a cash out letter of explanation.Credit Unions write their own rules!

The lender that I'm choosing to cash out with requires a 6-month seasoning period.

they still require internet.

My guess is that they will require it if you are adding a 3rd unit.

According to the Fair Housing Act and the Americans with Disabilities Act:Even if a landlord has a no pet policy in place, the law does not consider service animals as pets and therefore the service animal is exempt from such a restriction.Service animals are allowed anywhere a person would go, including food areas that would normally restrict an animal’s presence.Landlords cannot charge a pet deposit or pet fee for service animals, however the tenant is liable for any damage that the service animal may cause.Landlords can require written verification from the tenant’s health care provider that they are disabled but cannot ask for any specifics about the disability.Landlords can require written verification from the tenant’s health care provider that the service animal is needed.Landlords can request copies of the animal’s health records to prove the animal is in good health, parasite-free and immunized/vaccinated.Landlords can write warnings or even evict a tenant with a service animal if the animal is disturbing others, posing a threat to others or causing considerable damage to the property.In other words, you can ask for appropriate paperwork concerning the tenant’s need for the service animal and to verify the animal’s health. 

Many lenders require the funds to be used for business purpose.

It would require tweaking but I suspect you could get close on a lot of it.......just something I have been thinking about for a while and a guy like you could probably create something pretty cool!!   

@Martin Madelaire a MTM agreement or verbal agreement still has the same notice requirements.

Some lenders may require a second appraisal, if the value is over 20% of the initial cost.
