I just had to pay for some minor rent ready repairs like replacing the carpet and painting the interior.

You will also need about 6 months of reserves deposited in a traditional financial institution rather than a crypto account.The next step is to find the target property and calculate the acquisition costs and costs of construction along with the after-repair value. 

I am not sure how everyone else manages the repairs on  their properties, but I like the history.

However, I didn't lay out what that seller financing offer would look like because I'm really not sure if a deal can be made or how that financing would look.I'm hoping to find a way to get the home owner some money in her pocket if possible, although I need room for an investor to fix the issues and hopefully buy the lot back from the auto repair shop.

Deduct NEW property taxes after you buyDeduct home insurance costsDeduct maintenance percentage, typically 10%Deduct vacancy+tenant nonperformance percentage(we recommend 5% for Class A, 10% Class B, 20% Class C, good luck with Class D)Deduct whatever dollar/percentage of cashflow you wantNow, what you have left over is the amount for debt service.Enter it into a mortgage calculator, with current interest rate for an investment property, to determine your maximum mortgage amount.Divide the mortgage amount by either 75% or 80%, depending on the required down payment percentage - this is your tentative price to offer.If the property needs repairs, you'll want to deduct 110%-120% of the estimated repairs from this amount.Be sure to also research the ARV and make sure it's 10-20% higher than your tentative purchase price.As long as the ARV checks out, this is the purchase price to offer.It is probably significantly below the asking price.

As far as the 1099, that is for payment to owners if you manage for someone else or your vendors whom you pay for repairs and maintenance. 

Dealing with repairs, contractors, tenants etc is something I got sick off.A relative is renting out a garage in some empty lot and the thought crossed my mind of maybe buying some lot for car parking but I havent yet done any research on potential ROI on it yet.

Avoid common pitfalls like skipping due diligence, underestimating repairs, and overleveraging having reserves and a strong team is key.Good luck!

That, more than anything will help you answer the question "how much do I need to estimate for repairs"? 

If you’re paying off more than $1,500/mo I’d probably keep it barring any major upcoming capex. (3-5 years out so buyer wouldn’t automatically ask for it to be repaired at sale.)Good luck either way.
