I'm close to securing a contract on 4 unit property in Middletown, OH.

I understand I’ll have to hire a property Manager, I just don’t understand how security funds are handled Incase of emergency and immediate attention in the scenario where I may or may not be able to reach right away .

The tax lien (also called a fifa) exists prior to the tax sale and is recorded in the county's lien records - it's an unpaid debt secured by the property.  

A mortgage is then filed against the property to secure their investment.

I was thinking about being a real estate agent, but I'm missing social security number, so I can't be qualified as one.

Require a higher security deposit, last month's rent, both?

Your method makes sense for my higher rent units, but I'm not sure if it makes sense for lower rent units, which I'm already requiring first, last and security? 

If I have a tenant move in mid month I always collect a full first month's rent at move in (along with the security deposit).

Aside from that, they're usually much safer than an apartment and offer more security.

They agreeing to findings.2. complete repairs found by inspection and deduct from deposit3. clean carpet if they don't provide a receipt from a local, professional cleaner which is the condition they received it in. deduct from deposit if they didn't.4. if a pet was allowed, they must turn in a receipt showing it was treated for fleas. if If they dont it comes out of the deposit. if any damage from pet they're given an estimate of repair and sign an agreement that they will pay any excess not covered by deposit.5. touch up painting as needed, filters changed, fire alarm batteries updated.6. get keys from tenant and change locks. old locks go into inventory to be used in other properties.7. return their deposit with a letter documenting what expenses were paid out of it and a notice that they are welcome to return if they were a good tenant. they can use the statement for their future landlord as well. if they were not a good tenant, they go on a do not rent list for future reference with a copy of mive.iut inspection signed by them indicating damages and/or non-compliance behavior.
