Hi Eric,So there are roughly 4 methods to determine the price of a property.

Then just contact a realtor or use an online mortgage calculator to determine the payment. 

And the ability to complete of manage rehabs is an extremely rare and valuable skill.I would recommend evaluating whether multi or single family rentals work in your market, then determine which is more affordable compared to what offers the most cash flow.

The income can be labeled as ECI(Effectively connected income), FDAP(Fixed, Determined, Annual, Periodic) and FIRTPA. 

The reason is that any amount of cash you take or any amount you purchase less than you sell the IRS determines is taking profit (either cash direct or with borrowing less).  

@Scott Sambrook conventional (Fannie/Freddie) underwriting standards only require 6 months' seasoning before a new appraisal can be used to determine the value of a property for refinance purposes, but in my experience most lenders still want to see 12 months of ownership before they'll play along with that.

The interest will need to be traced to accurately determine tax treatment. 

What is the best way to determine a reasonable rent expectation?

The GRM varies by area, but this should help the appraiser determine value.

Inexperienced investors tend to (1) get exited about deals without having the experience, knowledge or ability to properly determine if indeed the deal is good, bad or mediocre, (2) take what the seller says as gospel not realizing most sellers will exaggerate, lie and or withhold vital information to get what they want, (3) engage people who will provide opinions for free rather than pay a competent professional, (4) get emotionally caught up in the deal and very defensive when receiving an opinion or information that doesn’t support their dream, and rationalize that more experienced people who point out flaws are “jealous, negative or haters”.Btw, no one can provide any knowledgeable answers to your questions without first analyzing the deal, your ability to come up with a down payment, your credit capacity and banking relations, if you have a track record, your experience with similar property ownership, etc.
