Im gona take the Robert Kiyosaki approach to answering this one,  Your question all be it a good one, its quite elementary, I think you should invest in education before you invest in a property. learn about construction, and costs, so you know what your looking at, Never just trust a contractor or inspector, ultimately your butt is on the line for their work.  

If I'm analyzing a property on the first run through I will plug in the properties' ~70% ARV for purchase price, low end rent, high end costs for repair, capex etc. and throw in 10% for future management costs.

It isn't very expensive and it could save your butt.

They are very helpful when trying to stay up to date and plugged in here on BP. 

Plug in the address and look around...Last piece of advice, don't get stuck in analysis paralysis...

Go kick butt.

For that an attorney is recommended.How much timber do you have.... to be viable in this market one needs at least a 5 acre stand of tree's that are too big at the butt to put your arms around ... and the first log  ( IE 40 ft up ) is clean ( that means no limbs )  big wolfy trees have little value  Wolf Tree = Huge limbs down low.the good news with Columbia county is the short truck to longview.

Twitter, LinkedIn, and all other social mediaPipeDrive, Zoho, Podio, Infusionsoft (I'd honestly do InvestorFuse vs. podio as it's more plug and play and simpler)Globiflow... don't need until you need true automation w/ podio.

You need to also take care of the following. 1.Fixing up a vacant rental so it can be rented out again.a.We had handy men to do most of this, but with 40 rentals my husband and I had to pitch in a do the labor ourselves as well.b.I would paint the house and garages.c.Husband would fix the repairs inside2.I would take care of the tenants.This entaileda.Taking care of advertising the homes (usually we had more than one vacancy at a time)b.Taking phone calls and screening tenantsc.Scheduling open housesd.Staging the housee.Interviewing the applicantsf.Making sure I double checked their application formsi.Criteriaii.Employersiii.Verifying funds and income3.Typing up the lease and making sure they understood the lease4.Then making sure the Tenants abided by the lease agreement5.Paid their rent on time6.And sent that Notice to Quit for Non Payment of Rent the very first day rent is late.On top of that I did my own evictions and I never lost a case and I dealt with the 36th District Court in Detroit.I won because I covered my butt by having everything in writing.I documented everything.Every phone call I made to them and every phone call they made to me.I never complained to a tenant because they called regarding a repair.I listened when they told me they couldn’t pay their rent, but even though I understood their problem, I made them pay their rent anyway.Landlording is about making tough decision and doing things you don’t like to have to do.Landlording is a Business.You have to not LOVE YOUR HOUSE.I can’t stress this enough.If you don’t know or understand that this is a business of evictions, damages, and injustices, and fixing this house up over and over again, you aren’t going to be happy let alone successful.How I wish I could be there for every new investor to help them understand what it’s like to be a landlord BEFORE YOU INVEST.But I can’t and that’s really a shame because it something every new investor should dig into before they invest.One last thing.

Most firms do not pay a salary and so you will only make money if you work your butt off and close sales.
