We have fixed multiple areas of the house including electrical, plumbing, added washers and dryers, added solar powered security lights, built an office, built a patio which increased the value of the house.

So far, it seems the options are:(1) Treat them the same as those staying shorter than 28 days(2) Treat them the same as those staying shorter than 28 days, but require security deposit(3) Treat them as long-term tenants, sign a lease with security deposit. (4) Treat them as long-term tenants, check background, sign a lease with security deposit.My main question is that if they have stayed longer than 28 days and refuse to leave at the end of their stay, landlords will need to start eviction processes no matter whether they have a lease with guests or not, correct?

Make sure the properties do not have health or safety violations, no biting dogs, no trampolines, security issues, force place renter insurance, communicate fast with kindness and no discrimination and you won't need a LLC. 

You could use a promissory note to secure it.

How do you guys find your private lenders, (I assume word of mouth and asking around) and how do you guys like to make this a good deal for the lender and secure the financing???

Only after that, she did feel secure enough to let any additional savings go towards me saving for real estate. 

(I understand most agent income comes from commission but would definitely love the security of a base salary even if it is minor.) 2.

I have created some interest, but I dont know what is actually realistic for terms.Example:  I find the deal, secure the financing, and do all the property management / tenant interaction...If i found someone else to put the entire or a large chunk of down payment what kind of profit/equity split is reasonable?  

I am creating an LLC in order to secure funding for our deal, and we will be splitting other associated costs that come along (i.e. for rehab). 

Offer your landlord $200 and if he doesn't like that then let him take you to court, or if he withholds your security deposit then take your landlord to small claims court.There is a normal amount of wear, dents, chips and discoloration that is an expectation with countertops.
