If you get a mortgage, the lender will want to check surveys, appraisals, and title issues, things that don't always happen when buying owner financed. 

It covers some of what you have on there (financing/survey/inspection) and you can add the others in additional provisions.

Have a updated title search and survey done along with a house a appraisal and inspection to know what needs to be done.

Should i get a survey done to mark the property boundary?

One of the contingencies on this property with Fannie Mae was they completed a Flood Elevation Survey.  

I'm looking for some help on the numbers.This would be my first BRRRR deal so kind of nervous.Purchase price $281KClosing costs (Attorney fee 995 +inspection 600 +survey 250) = 1845Total = 282,845Rent estimate = $2400Prop mgmt = 230 (10%)Tenant turnover = 110 (5%)Prop maintenance = 110 (5%)Capex = 110 (5%)Tax = $350Ins = $100 (guestimate)Reno budget = $25KARV = $330KRefinance: P+I = $1275 (70% refi)Prop mgmt = 230 (10%)Tenant turnover = 110 (5%)Prop maintenance = 110 (5%)Capex = 110 (5%)Tax = $350Ins = $100 (guestimate)Net = 2400-2285 = $115 /mo.I know it's not a lot of cashflow, but A class neighborhood and potential equity make it a sweet deal.

If anything I'd take that $ and get a survey to make sure the fence isn't encroaching on my property.

In all I was out the cost of the flight, rental car, and inspection.In general however, the Due Diligence (DD) period is the time when you "kick the tires" and look at every aspect of a property - order your inspections, get trades to bid on CapEx, review leases, look at expenses, city/county records, property line surveys, etc.

Folks who don't have a lot of money typically aren't equipped to handle the financing of land, running utilities, surveys, building, etc.

...Do you all have resident surveys?
