Pre-Sale contracts can allow a buyer to build a year's worth of equity with just $500 earnest deposit.

(Ended up eating about 6o days of no paid rent so really not that bad after the security deposit.)

[to receive certified deposit  list an estimated/ deductions  for them ]  but wanted to know. 

Some landlords would either request a double security deposit (if allowed in your state) or jack up the rent to take someone with a history of past court judgments...as well as providing only a month to month lease to be able to get her out quicker than an eviction should she go back to her previous habits.

Those are areas that, if they match with good data, are your target markets because you either have more personal knowledge of the area or have real boots on the ground who you trust already.

If you accept it be sure to put it in your escrow account with your deposits and only take rent out each month as it is due. 

Operating expenses include (but are not limited to): taxes, insurance, management, maintenance, entity maintenance, advertising, utilities (at least during vacancies), legal fees, damage done by tenants (over the security deposit), vacancies, setouts, lawsuits, and capital expenses (not technically an operating expense).Stated another way, the 50% rule, which is generally considered to be fairly close to actual expenses, states that …50% of your gross rents will be taken up by expenses, such as property tax insurance vacancy property management maintenance capital repairs legals and accounting.From the remaining 50% you service your debt, if any, and the remaining is your profit.

Therefore, you would need to make sure their personality, vision, and goals match with yours. right?

Giving them right of refusal to match competing offers, renewals for 21 years, and if you break it they are allowed to collect 75% of gross revenues (they only get 50% now)  for the remainder of the lease and that 21 years of renewals. 

Also, should I require additional deposit from the new roommate?
